What is the definition of a linear system?

A linear system is a mathematical model that consists of linear equations, where the variables are raised to the power of 1 and do not have any product or division involving the variables. These systems can be represented by matrices and can be solved using various methods such as substitution, elimination, or matrix operations.

What are the two methods for solving linear systems?

The two methods for solving linear systems are substitution and elimination. Substitution involves solving one equation for one variable and substituting that expression into the other equation. Elimination involves adding or subtracting equations to eliminate a variable and solve for the remaining variables. Both methods are commonly used in algebra to find the solutions to systems of linear equations.

Describe the process of solving a linear system by substitution.

In solving a linear system by substitution, we isolate one variable in one equation and substitute that expression into the other equation. This helps us to eliminate the variable that we substituted, leaving us with one equation and one unknown, which we can then solve to find the value of that unknown variable. We then substitute this value back into one of the original equations to find the value of the other variable. This process allows us to find the solution where the two equations intersect on a graph, representing the values that satisfy both equations simultaneously.

When do you use the substitution method to solve a linear system?

The substitution method is used to solve a linear system when one of the equations can be solved for one variable in terms of the other variable, making it easier to substitute this expression into the other equation to find the values of the variables. This method is particularly useful when one equation is already solved for a variable or when one equation can be easily manipulated to isolate a variable.

How do you choose which equation to solve for a variable in the substitution method?

When using the substitution method to solve a system of equations, you typically choose the equation to solve for a variable by looking for the equation that has one variable already isolated. By isolating a variable in one of the equations, you can easily substitute that expression into the other equations to eliminate one variable and solve for the other. This allows you to simplify the system of equations and find the solution more efficiently.

What is the next step after solving for a variable in the substitution method?

After solving for a variable in the substitution method, you should substitute the value of the solved variable back into one of the original equations to find the value of the other variable. This will allow you to find the solution for both variables in the system of equations.

How do you check your solution in the substitution method?

To check your solution in the substitution method, you need to substitute the values of the variables from your solution back into the original equations. If the substituted values satisfy all the original equations, then your solution is correct. If any of the equations do not hold true with the substituted values, then your solution is not correct.

Can you always solve a linear system by substitution? Why or why not?

Yes, a linear system can always be solved by substitution as long as the system is consistent and has a unique solution. Substitution involves isolating one variable in one equation and then substituting this expression into the other equation, which allows for solving the system of equations by finding the values of the variables. However, if the system is inconsistent or has infinitely many solutions, substitution may not provide a clear solution.

What is the main advantage of using the substitution method to solve linear systems?

The main advantage of using the substitution method to solve linear systems is that it is straightforward and easy to understand. It involves isolating one variable in one of the equations and then substituting that value into the other equation, which simplifies the system down to a single equation with one variable. This method is efficient and can be used for systems with any number of variables as long as there is one equation that can easily be rearranged for substitution.

Can you solve a linear system by substitution if one of the equations is not in standard form?

Yes, you can still solve a linear system by substitution even if one of the equations is not in standard form. To do so, you would first need to rewrite the non-standard equation so that it is in standard form (ax + by = c). Once all the equations are in standard form, you can then proceed with substituting one equation into the other and solving for the variables to find the solution to the system.
