x in (-oo:+oo)
2-((3/2)*(x+1)) = 6*x-9 // - 6*x-9
2-((3/2)*(x+1))-(6*x)+9 = 0
(-3/2)*(x+1)-6*x+2+9 = 0
2-3/2*(x+1)-6*x+9 = 0
2-3/2*(x+1)-6*x+9 = 0
2-15/2*x-3/2+9 = 0
1/2-15/2*x+9 = 0
19/2-15/2*x = 0
19/2-15/2*x = 0
19/2-15/2*x = 0 // - 19/2
-15/2*x = -19/2 // : -15/2
x = -19/2/(-15/2)
x = 19/15
x = 19/15
