((2*x+15)^1)/2-2 = ((6*x+1)^1)/2 // - ((6*x+1)^1)/2
((2*x+15)^1)/2-(((6*x+1)^1)/2)-2 = 0
(2*x+15)/2-((6*x+1)/2)-2 = 0
(2*x+15)/2+(-1*(6*x+1))/2-2 = 0
(2*x+15)/2+(-1*(6*x+1))/2+(-2*2)/2 = 0
2*x-1*(6*x+1)-2*2+15 = 0
14-4*x-4 = 0
10-4*x = 0
(10-4*x)/2 = 0
(10-4*x)/2 = 0 // * 2
10-4*x = 0
10-4*x = 0 // - 10
-4*x = -10 // : -4
x = -10/(-4)
