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 for x: 2d + 7 = 9

Back

x = 1

Front

What is the first step to solve the equation 4x + 22 = -34?

Back

Subtract 22 from both sides.

Front

Solve for x: 4x + 22 = -34

Back

x = -14

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 for x: -3x - 12 = 15

Back

x = -9

Front

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

Back

Add 13 to both sides.

Front

Solve for x: 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 for x: x/3 + 5 = -1

Back

x = -18
