Sorry it is x = 8 I made a mistake.


Ok, we need to solve for x

5(8 + 7) = 5 • x + 5 • 7

First do what is inside of the parenthesizes(8+7)
5(8 + 7) = 5 • x + 5 • 7
5(15) = 5 * x + 5 * 7

Next times everything together
5(15) = 5 * x + 5 * 7
75 = 5x + 35

Now lets get 5x by its self by using the addition property.

75 = 5x + 35
75 - 35 = 5x
40 = 5x

Next use the division perperty to get x alone. Divide by 5 on both sides of the =
40 /5 = 5x/5
8 = x

x= 8
