What are two-step equations?
Two-step equations are algebraic equations that require two mathematical operations to solve for the unknown variable. The goal is to isolate the variable by performing two steps, such as adding or subtracting a number and then multiplying or dividing by another number, to determine its value. This process helps solve for the unknown variable and find the solution to the equation.
How do you solve a two-step equation?
To solve a two-step equation, start by isolating the variable term on one side of the equation. First, undo any addition or subtraction by performing the opposite operation. Next, undo any multiplication or division by performing the inverse operation. The goal is to get the variable term isolated on one side and the constant term on the other side. Finally, solve for the variable by performing any necessary arithmetic operations.
Can you provide an example of a two-step equation and its solution?
Sure, an example of a two-step equation is 3x + 5 = 11. To solve this equation, first, subtract 5 from both sides to isolate the variable: 3x = 6. Then, divide by 3 on both sides to solve for x: x = 2. Therefore, the solution to the equation 3x + 5 = 11 is x = 2.
What is the purpose of isolating the variable in a two-step equation?
The purpose of isolating the variable in a two-step equation is to solve for its value by performing a series of inverse operations to isolate the variable on one side of the equation. This process allows us to find the specific value of the variable that makes the equation true and helps us understand the relationship between the different components of the equation.
What is the first step in solving a two-step equation?
The first step in solving a two-step equation is to isolate the variable term by performing the inverse operation of the operations applied to the variable term in the equation. This usually involves performing addition or subtraction first, followed by multiplication or division.
How do you determine which operation to perform first in a two-step equation?
To determine which operation to perform first in a two-step equation, you typically start by identifying and simplifying any operations within parentheses or brackets. Then, you would proceed by performing any addition or subtraction operations before multiplication or division operations. Following the order of operations (parentheses, exponents, multiplication and division, addition and subtraction) ensures that you solve the equation correctly and get the accurate solution.
Can you explain the process of combining like terms in a two-step equation?
To combine like terms in a two-step equation, you first need to isolate the variable terms on one side of the equation by performing inverse operations. This involves undoing addition or subtraction first by performing the opposite operation. Then, you move on to undoing multiplication or division by performing the opposite operation. Once the variable term is isolated, you can combine the like terms on both sides of the equation by simplifying any constants or coefficients that are similar. Finally, you solve for the variable to find the solution to the equation.
What is the second step in solving a two-step equation?
The second step in solving a two-step equation is to isolate the variable by performing the opposite operation that is being applied to it. This typically involves using the inverse operation, such as division if multiplication was used in the first step, or subtraction if addition was used in the first step. By applying the correct inverse operation, you can determine the value of the variable and successfully solve the equation.
How do you undo addition or subtraction in a two-step equation?
To undo addition or subtraction in a two-step equation, you should perform the inverse operation. If there was addition, you would subtract the same value from both sides of the equation. If there was subtraction, you would add the same value to both sides of the equation. This step helps to isolate the variable and solve for its value.
How do you check your answer to a two-step equation?
To check your answer to a two-step equation, you can substitute the solution you found back into the original equation and see if both sides are equal. Simply replace the variable with your solution and perform the operations to verify if the equation holds true. If both sides are equal, then your answer is correct; if not, there may have been an error in your calculations.
