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 4(2x + 8) - 3x = 47?

Back

Distribute the 4 to both terms inside the parentheses.

Front

Solve for x: 4(2x + 8) - 3x = 47

Back

x = 3

Front

What is the process to isolate x in the equation x/4 - 3 = 9?

Back

Add 3 to both sides and then multiply by 4.

Front

Solve for x: x/4 - 3 = 9

Back

x = 48

Front

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

Back

To isolate a 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 for a: 7 + a/3 = 5

Back

a = -6

Front

What is the combined like terms in the equation 2x + 3x + 4 = 44?

Back

2x + 3x = 5x.

Front

Solve for x: 2x + 3x + 4 = 44

Back

x = 8

Front

What is the first step to solve the equation -11 + 3(b + 5) = 7?

Back

Add 11 to both sides.
