Unit 2 - Equations

Which of the following equations require you to use the Distributive Property first?

Select all that apply.

• 6x-8=7(x+2)

• 7n-5=3

• 2(a-9)=9a+1

• 4-9y=8+4y-2

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides
• Add the 2a and a 
• Distribute 4 to a and -5
• Distribute -4 to a and -5
