(5/2)*(1-(2*x))+15/2 = -4*x // + -4*x
(5/2)*(1-(2*x))-(-4*x)+15/2 = 0
(5/2)*(1-2*x)+4*x+15/2 = 0
5/2*(1-2*x)+4*x+15/2 = 0
(2*5/2*(1-2*x))/2+(2*4*x)/2+15/2 = 0
2*5/2*(1-2*x)+2*4*x+15 = 0
5-2*x+15 = 0
20-2*x = 0
(20-2*x)/2 = 0
(20-2*x)/2 = 0 // * 2
20-2*x = 0
20-2*x = 0 // - 20
-2*x = -20 // : -2
x = -20/(-2)
x = 10
