Expressions and Equations Distributing and One Step

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

Expand the expression.
5(x + 2)

• 5x + 10

• 5x + 7

• 4x + 7

• 5x + 3

Simplify the expression: 
36a+12-6a-7 

• 30a+5

• 30a-5 

• 42a+19 

• 42

Choose the expression that is equivalent to: 12( 2r + 5)

• 24r - 60

• 24r + 12

• 24 + 60

• 24r + 60

Distribute:

Choose an expression that is equivalent to

4(2a -y)

• 8a - 4y

• 42a - 4y

• 8ay

• 12

What is the first step you should take to solve this problem?

-3 ( x - 2 ) = -8 + 9x

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

Which of the following is equivalent to 4(2x + 3)

• 8x + 12

• 8x + 3

• 8x - 12

• 20x

-3(n-8)

• 3n-8

• -3n-24

• -3n+24
