Question

Ok, so the answer book doesn't have my answer: 3/4 x + 5/6 = 5x - 125/3. I get x = 15?

Answer 1

does x=15 work?

Answer 2

3/4 x + 5/6 = 5x - 125/3 ; multiply by 3

9/4 x + 15/6 = 15x - 125 ; since 15 and 6 have a common factor of 3, simplify

9/4 x + 5/2 = 15x - 125 ; multiply by 2

9(2)/4 x + 5 = 30x - 250 ; simplify the 2/4

9/2 x + 5 = 30x - 250 ; multiply by 2 again

9x + 10 = 60x - 500 ; solve for x

510 = 51x

x = 10

Answer 3
