Two 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: x/7 - 2 = 8

Back

x = 70

Front

Solve for w: -6w + 1 = -11

Back

w = 2

Front

Solve: x/3 + 5 = -1

Back

x = -18

Front

Solve: x/5 - 13 = 20

Back

x = 165

Front

What is the first step in solving the equation x/7 - 2 = 8?

Back

Add 2 to both sides of the equation.

Front

What is the second step in solving the equation x/7 - 2 = 8?

Back

Multiply both sides by 7.

Front

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

Back

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

Front

What is the solution to the equation -6w + 1 = -11?

Back

w = 2

Front

How do you check if your solution to a two-step equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.
