(3-(5*x))/3-((1-(8*x))/4) = (4*(3-(5*x))-(3*(1-(8*x))))/12 // - (4*(3-(5*x))-(3*(1-(8*x))))/12
(3-(5*x))/3-((1-(8*x))/4)-((4*(3-(5*x))-(3*(1-(8*x))))/12) = 0
(3-5*x)/3-((1-8*x)/4)-((4*(3-5*x)-3*(1-8*x))/12) = 0
(3-5*x)/3+(-1*(1-8*x))/4+(-1*(4*(3-5*x)-3*(1-8*x)))/12 = 0
(4*12*(3-5*x))/(3*4*12)+(-1*3*12*(1-8*x))/(3*4*12)+(-1*3*4*(4*(3-5*x)-3*(1-8*x)))/(3*4*12) = 0
4*12*(3-5*x)-1*3*12*(1-8*x)-1*3*4*(4*(3-5*x)-3*(1-8*x)) = 0
48*x-48*x-108+108 = 0
0 = 0
0/(3*4*12) = 0
0/(3*4*12) = 0 // * 3*4*12
0 = 0
0 = 0
x należy do R
