3*((4*x)/2+1/2)+(4*x)/5 = (11*x)/5+7/2 // - (11*x)/5+7/2
3*((4*x)/2+1/2)+(4*x)/5-((11*x)/5)-(7/2) = 0
3*((4*x)/2+1/2)+(4*x)/5+(-11/5)*x-7/2 = 0
3*(2*x+1/2)+(4*x)/5+(-11*x)/5-7/2 = 0
(2*3*5*(2*x+1/2))/(2*5)+(2*4*x)/(2*5)+(-11*2*x)/(2*5)+(-7*5)/(2*5) = 0
2*3*5*(2*x+1/2)+2*4*x-11*2*x-7*5 = 0
68*x-22*x-35+15 = 0
46*x-35+15 = 0
46*x-20 = 0
(46*x-20)/(2*5) = 0
(46*x-20)/(2*5) = 0 // * 2*5
46*x-20 = 0
46*x-20 = 0 // + 20
46*x = 20 // : 46
x = 20/46
x = 10/23
