Unit 4: Whole Number One-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step by performing the same operation on both sides to isolate the variable.

Front

Solve for y: y - 14 = 66

Back

y = 80

Front

What is the first step to solve x - 6 = 13?

Back

Add 6 to both sides to isolate x.

Front

Solve for x: x + 6 = 13

Back

x = 7

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 for x: 17 = x + 3

Back

x = 14

Front

What operation would you use to solve x ÷ 2 = 12?

Back

Multiply both sides by 2.

Front

Solve for x: x ÷ 2 = 12

Back

x = 24

Front

What is the solution to the equation x - 32 = 49?

Back

x = 81

Front

What is the purpose of checking your solution in an equation?

Back

To verify that the solution satisfies the original equation.
