(2/5)*(4*x+3) = 3*(2-(2*x))+18 // - 3*(2-(2*x))+18
(2/5)*(4*x+3)-(3*(2-(2*x)))-18 = 0
(2/5)*(4*x+3)-3*(2-2*x)-18 = 0
2/5*(4*x+3)-3*(2-2*x)-18 = 0
2/5*(4*x+3)-3*(2-2*x)-18 = 0
38/5*x-18-24/5 = 0
38/5*x-114/5 = 0
38/5*x-114/5 = 0
38/5*x-114/5 = 0 // + 114/5
38/5*x = 114/5 // : 38/5
x = 114/5/38/5
x = 3
