What is the first step in solving a one-variable equation?

The first step in solving a one-variable equation is to isolate the variable on one side of the equation by performing inverse operations. These operations include adding, subtracting, multiplying, or dividing by a certain value in order to get the variable alone on one side of the equation.

How do you isolate the variable in an equation with fractions?

To isolate a variable in an equation with fractions, you can follow a few steps. First, get rid of any denominators by multiplying both sides of the equation by the common denominator. Next, perform any necessary operations to simplify the equation and isolate the variable you want to solve for. Remember to apply the same operations to both sides of the equation to maintain its balance. Finally, solve for the variable by performing any remaining operations and simplify the result if needed.

What is the order of operations when solving an equation?

When solving an equation, you should follow the order of operations, which is usually remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). You should first simplify anything inside parentheses, then solve any exponents, followed by any multiplication and division, and finally addition and subtraction. Remember to work step by step, following this order, to ensure you solve the equation correctly.

How do you solve an equation with variables on both sides?

To solve an equation with variables on both sides, start by simplifying both sides of the equation by combining like terms. Then, move all the variable terms to one side of the equation and the constant terms to the other side by using inverse operations like addition, subtraction, multiplication, and division. Finally, solve for the variable by isolating it on one side of the equation. Remember to perform the same operation on both sides of the equation to maintain its balance and find the value of the variable.

How can you check your solution in an equation?

To check your solution in an equation, you simply need to substitute the solution back into the original equation and see if it satisfies the equation. If the solution makes both sides of the equation equal, then it is correct. If the solution does not satisfy the equation, then it is incorrect. This process helps verify the accuracy of the solution you have found.

What do you do if you end up with a zero on one side of the equation?

If you end up with a zero on one side of the equation, the next step is typically to simplify or rewrite the equation to isolate the variable on the other side of the equation. This may involve moving terms from one side to the other by using inverse operations, such as adding, subtracting, multiplying, or dividing. By properly manipulating the equation, you can solve for the unknown variable and find the desired solution.

Can every equation be solved?

Not all equations can be solved. Some equations may have no solution, an infinite number of solutions, or solutions that involve complex numbers. The solvability of an equation depends on its specific characteristics and properties.

How do you handle equations with decimals?

To handle equations with decimals, you can first multiply the entire equation by a power of 10 to eliminate the decimals. This will allow you to work with whole numbers instead. After solving the equation with whole numbers, you can divide the final result by the same power of 10 to convert it back to a decimal, if needed. Alternatively, you can also choose to work with decimals directly by keeping track of the decimal places throughout your calculations.

What is the difference between an identity and a contradiction in an equation?

An identity in an equation is a statement that remains true for all values of the variables involved, such as \(x^2 - y^2 = (x + y)(x - y)\). In contrast, a contradiction in an equation is a statement that is always false, regardless of the values the variables take, such as \(x = 2\) and \(x = 5\) in the same equation.

Is it possible for an equation to have no solution?

Yes, it is possible for an equation to have no solution. This typically occurs when the equation represents contradictory conditions, such as 2 = 3, or when the variable in the equation is eliminated through simplification, leaving no valid solution. In such cases, the equation does not have a solution.
