5x -15 + 3 -8x = 13
5x -12 -8x = 13
5x -8x =13 -12
-3x = 1
x = -1/3
-x^2 - 2x - 5=0
-(x^2 + 2x + 1) -4=0
(x +1)^2= -4
=> Impossible. There is no x

yellow: 4/3 - 3/4 = 16/12-9/12 = 7/12
green: 5/4 - 3/4 = 5/4-3/4 = 2/4
blue: 7/8 - 3/4 = 14/16-12/16 = 2/16
7/12 + 2/4 + 2/16 = 28/48 + 24/48 + 6/48 =
58/48 or 1 5/24
