x in (-oo:+oo)
(1/2)*(3*x-6)+(1/3)*(4*x-5) = (1/5)*(10*x-15)+3 // - (1/5)*(10*x-15)+3
(1/2)*(3*x-6)+(1/3)*(4*x-5)-((1/5)*(10*x-15))-3 = 0
(1/2)*(3*x-6)+(1/3)*(4*x-5)+(-1/5)*(10*x-15)-3 = 0
1/2*(3*x-6)+1/3*(4*x-5)-1/5*(10*x-15)-3 = 0
1/2*(3*x-6)+1/3*(4*x-5)-1/5*(10*x-15)-3 = 0
17/6*x-2*x-14/3-3+3 = 0
5/6*x-3-5/3 = 0
5/6*x-14/3 = 0
5/6*x-14/3 = 0
5/6*x-14/3 = 0 // + 14/3
5/6*x = 14/3 // : 5/6
x = 14/3/5/6
x = 28/5
x = 28/5
