2-Step Equations

Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in a 2-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order of how they appear in the equation.

Front

Solve for x: -10 = 4x + 6

Back

x = -4

Front

Solve for x: -8x + 3 = 27

Back

x = -3

Front

Solve for x: 2x + 6 = 18

Back

x = 6

Front

Solve for x: 12 = 5x + 17

Back

x = -1

Front

Solve for x: 3x - 7 = -16

Back

x = -3

Front

What is the first step to solve the equation 4x + 6 = -10?

Back

Subtract 6 from both sides to get 4x = -16.

Front

What is the second step to solve the equation 4x = -16?

Back

Divide both sides by 4 to find x = -4.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation, such as addition and subtraction or multiplication and division.
