(2*x+9)/3+2/3 = (-3*x)/2 // - (-3*x)/2
(2*x+9)/3-((-3*x)/2)+2/3 = 0
(2*x+9)/3+(3/2)*x+2/3 = 0
(2*x+9)/3+(3*x)/2+2/3 = 0
(2*(2*x+9))/(2*3)+(3*3*x)/(2*3)+(2^2)/(2*3) = 0
2*(2*x+9)+3*3*x+4 = 0
13*x+4+18 = 0
13*x+22 = 0
(13*x+22)/(2*3) = 0
(13*x+22)/(2*3) = 0 // * 2*3
13*x+22 = 0
13*x+22 = 0 // - 22
13*x = -22 // : 13
x = -22/13
x = -22/13
