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: 9 + 3x = 10

Back

x = 1/3

Front

What is the first step to solve the equation 2d + 7 = 9?

Back

Subtract 7 from both sides to isolate the term with the variable.

Front

Back

d = 1

Front

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

Back

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

Front

Solve: x/5 - 13 = 20

Back

x = 165

Front

What is the second step to solve the equation 11 = 3z + 5?

Back

Subtract 5 from both sides to isolate the term with the variable.

Front

Solve: 11 = 3z + 5

Back

z = 2

Front

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

Back

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