What is the solution to the equation?

5 (8 + 7) = 5 • x + 5 • 7

A.

x = 1

B.

x = 5

C.

x = 7

D.

x = 8

D. X=8 distribute the 5 to the 8 and 7 which is 40 + 35 = 5 times x + 5 times 7 Multiply 5 times x and 5 and 7. Add left side to equal 75. Subtract 35 from both sides. Divide by 5 on both sides. Get x = 8 5 (8+7) = 5x+35 40 + 35 = 5x + 35 75 = 5x + 35 40 = 5x X=8
