One-Step and Two-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 the equation: 6b = 30

Back

b = 5

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to isolate the variable.

Front

Solve the equation: x + 12 = 20

Back

x = 8

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve the equation: -3 + \frac{r}{6} = 1

Back

r = 24

Front

What is the first step to solve the equation: 2t - 2 = -4?

Back

Add 2 to both sides to isolate the term with the variable.

Front

Solve the equation: -4 = 2t - 2

Back

t = -1

Front

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

Back

To verify that the solution satisfies the original equation.

Front

Solve the equation: 2x + 10 = 16

Back

x = 3
