x in (-oo:+oo)
(2/5)*(2*x+9) = 2*(3-(3*x))+18 // - 2*(3-(3*x))+18
(2/5)*(2*x+9)-(2*(3-(3*x)))-18 = 0
(2/5)*(2*x+9)-2*(3-3*x)-18 = 0
2/5*(2*x+9)-2*(3-3*x)-18 = 0
2/5*(2*x+9)-2*(3-3*x)-18 = 0
34/5*x-18-12/5 = 0
34/5*x-102/5 = 0
34/5*x-102/5 = 0
34/5*x-102/5 = 0 // + 102/5
34/5*x = 102/5 // : 34/5
x = 102/5/34/5
x = 3
x = 3
