Solving Two-Step Equations

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

What is the first step to solve the equation -4x + 1 = 21?

Back

Subtract 1 from both sides to isolate the term with the variable.

Front

Solve for x: -4x + 1 = 21

Back

x = -5

Front

What is the first step to solve the equation 10 - 3y = 4?

Back

Subtract 10 from both sides.

Front

Solve for a: -5 - 6a = -59

Back

a = 9

Front

What is the first step to solve the equation -5 + 7k = -19?

Back

Add 5 to both sides.

Front

Solve for k: -5 + 7k = -19

Back

k = -2

Front

What is the first step to solve the equation 7k - 14 = 42?

Back

Add 14 to both sides.

Front

Solve for k: 7k - 14 = 42

Back

k = 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.
