Solving 2 step equations

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What is the FIRST step in solving a two-step equation?

Back

Add or subtract the constant term from both sides of the equation.

Front

What is the SECOND step in solving a two-step equation?

Back

Multiply or divide both sides of the equation by the coefficient of the variable.

Front

What does it mean to isolate the variable?

Back

To isolate the variable means to get the variable alone on one side of the equation.

Front

If the equation is 2x + 3 = 11, what is the first step to solve for x?

Back

Subtract 3 from both sides to get 2x = 8.

Front

In the equation 2x = 8, what is the next step to find x?

Back

Divide both sides by 2 to get x = 4.

Front

What is the purpose of checking your solution in an equation?

Back

To verify that the solution satisfies the original equation.

Front

What is the solution to the equation 5x - 2 = 3?

Back

x = 1.

Front

How do you solve the equation x/4 + 2 = 5?

Back

First, subtract 2 from both sides to get x/4 = 3, then multiply both sides by 4 to find x = 12.

Front

What is the first operation to perform in the equation 3x + 4 = 10?

Back

Subtract 4 from both sides to get 3x = 6.
