((7/2)*x+5)/(1/4)-(9*x) = 3*(x-(1/3))-5 // - 3*(x-(1/3))-5
((7/2)*x+5)/(1/4)-(3*(x-(1/3)))-(9*x)+5 = 0
((7/2)*x+5)/(1/4)-3*(x-1/3)-9*x+5 = 0
(7/2*x+5)/1/4-3*(x-1/3)-9*x+5 = 0
(7/2*x+5)/1/4+(-3*1/4*(x-1/3))/1/4+(-9*1/4*x)/1/4+(1/4*5)/1/4 = 0
7/2*x-3*1/4*(x-1/3)-9*1/4*x+1/4*5+5 = 0
11/4*x-9/4*x+5/4+21/4 = 0
1/2*x+5/4+21/4 = 0
1/2*x+13/2 = 0
(1/2*x+13/2)/1/4 = 0
(1/2*x+13/2)/1/4 = 0 // * 1/4
1/2*x+13/2 = 0
1/2*x+13/2 = 0 // - 13/2
1/2*x = -13/2 // : 1/2
x = -13/2/1/2
x = -13
