Solving 2-Step Equations

Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable. For example, in the equation 3x - 7 = 32, you first add 7 to both sides and then divide by 3.

Front

Solve the equation: 3x - 7 = 32

Back

x = 13

Front

What is the first step in solving the equation 3x - 7 = 32?

Back

Add 7 to both sides.

Front

Solve the equation: 2x - 3 = 1

Back

x = 2

Front

What is the first step in solving the equation 2x - 3 = 1?

Back

Add 3 to both sides.

Front

Back

x = 100

Front

Back

Add 6 to both sides.

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 by itself, making it easier to solve.

Front

What is the solution to the equation 5x + 10 = 35?

Back

x = 5

Front

What is the first step in solving the equation 5x + 10 = 35?

Back

Subtract 10 from both sides.
