Question

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

Answer 1

5(15)=5(x)+35 - Add 8+7 then multiply 5 and 7\

75=5x+35 - Multiply 15 and 5 and then multiply 5 and x

75-35= 5x - Bring the 35 over and change the sign

40=5x - Subtract 75 and 35

8=x - divide 40 and 5

Your final answer will be "D" x=8... Hope this helped :)))
