Question

Solve 3(x – 5) + 5(4 – x) = 8.
Select one:
a. x = -3/2
b. x = -13/2
c. x = 13/8
d. x = 3/8

Answer 1

I'd say a. but i've got 3/2 and not-3/2.

Answer 2

Distributive Property:
3x-15+20-5x = 8 Combine like terms on both sides
-2x+5 = 8 Subtract the number that is added to the x. Always do the opposite.
-5 -5
-2x = 3 Divide by -2
x = -0.6
