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 are applied.

Front

Solve for x: 4(x + 8) = 44

Back

x = 3

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for x: x/5 - 13 = 20

Back

x = 165

Front

Solve for s: 9 = 2s + 1

Back

s = 4

Front

Solve for x: x/4 + 11 = 20

Back

x = 36

Front

What is the first step to solve the equation 2x + 5 = 15?

Back

Subtract 5 from both sides to get 2x = 10.

Front

What does it mean to perform the inverse operation?

Back

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

Front

If you have the equation x - 7 = 3, what is the first step to solve for x?

Back

Add 7 to both sides to get x = 10.
