Two-Step Equations Review

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 how they are applied.

Front

Solve for a: 3 + (1/4)a = 31

Back

a = 112

Front

Solve for n: 3n + 4 = 7

Back

n = 1

Front

Solve for c: 4c - 6 = 2

Back

c = 2

Front

What is the first step to solve 5b - 6 = 24?

Back

Add 6 to both sides and divide both sides by 5.

Front

What is the first step to solve 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

What does it mean to perform inverse operations?

Back

Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.

Front

What is the solution to the equation 2x + 5 = 15?

Back

x = 5

Front

How do you check your solution in a two-step equation?

Back

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