3-((3*x+4)/5) = x/2 // - x/2
3-((3*x+4)/5)-(x/2) = 0
(-1*(3*x+4))/5-x/2+3 = 0
(-1*2*(3*x+4))/(2*5)+(5*(-x))/(2*5)+(2*3*5)/(2*5) = 0
5*(-x)-1*2*(3*x+4)+2*3*5 = 0
30-11*x-8 = 0
22-11*x = 0
(22-11*x)/(2*5) = 0
(22-11*x)/(2*5) = 0 // * 2*5
22-11*x = 0
22-11*x = 0 // - 22
-11*x = -22 // : -11
x = -22/(-11)
x = 2
