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

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

Back

To isolate a variable, perform inverse operations in the reverse order of operations.

Front

Solve the equation: 4n - 7 = 45

Back

n = 13

Front

Solve the equation: 7 + 9n = 187

Back

n = 20

Front

Solve the equation: 7r + 7 = -70

Back

r = -11

Front

Solve the equation: -6 - v = -17

Back

v = 11

Front

Solve the equation: 5v - 4 = -64

Back

v = -12

Front

What is the first step to solve the equation 4n - 7 = 45?

Back

Add 7 to both sides of the equation.

Front

What is the second step to solve the equation 4n - 7 = 45 after adding 7?

Back

Divide both sides by 4.
