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

Solve: -3x - 12 = 15

Back

x = -9

Front

What is the first step to solve the equation x/12 - 8 = -4?

Back

Add 8 to both sides of the equation.

Front

Solve: x/12 - 8 = -4

Back

x = 48

Front

What does it mean to isolate the variable in an equation?

Back

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

Front

Solve: -5t + 9 = 24

Back

t = -3

Front

What is the second step to solve the equation x/5 - 13 = 20?

Back

Multiply both sides by 5.

Front

Solve: x/5 - 13 = 20

Back

x = 165

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo operations and isolate the variable.

Front

Solve: 7 + a/3 = 5

Back

a = -6
