One-Step and Two-Step Equations

Front

What is a one-step equation?

Back

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

Front

Solve: x + 12 = 20

Back

x = 8

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two steps to solve, typically involving two different operations.

Front

Solve: -9x - 12 = 33

Back

x = -5

Front

Solve: 6b = 30

Back

b = 5

Front

What is the first step to solve the equation 2m - 6 = 10?

Back

Add 6 to both sides of the equation.

Front

Solve: 2m - 6 = 10

Back

m = 8

Front

What does it mean to isolate the variable in an equation?

Back

Isolating the variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

Solve: -3 + 2x = -1

Back

x = 1

Front

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

Back

To verify that the solution satisfies the original equation.
