Solving 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

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

Back

To isolate a variable, perform the inverse operations in the reverse order of how they appear in the equation.

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for s: 9 = 2s + 1

Back

s = 4

Front

Solve for k: 2k + 12 = -4

Back

k = -8

Front

Solve for d: 5d - 6 = 9

Back

d = 3

Front

Solve for m: -5 = 3m - 14

Back

m = 3

Front

What is the first step to solve the equation 3n + 4 = 7?

Back

Subtract 4 from both sides to get 3n = 3.

Front

What is the second step to solve the equation 3n = 3?

Back

Divide both sides by 3 to find n = 1.

Front

What does it mean to perform the inverse operation?

Back

An inverse operation reverses the effect of the original operation, such as addition and subtraction or multiplication and division.
