x in (-oo:+oo)
5*(1/6)*x = (7/9)*(2*x+3) // - (7/9)*(2*x+3)
5*(1/6)*x-((7/9)*(2*x+3)) = 0
(-7/9)*(2*x+3)+5*(1/6)*x = 0
(5*x)/6-7/9*(2*x+3) = 0
(-7/9*6*(2*x+3))/6+(5*x)/6 = 0
5*x-7/9*6*(2*x+3) = 0
-13/3*x-14 = 0
(-13/3*x-14)/6 = 0
(-13/3*x-14)/6 = 0 // * 6
-13/3*x-14 = 0
-13/3*x-14 = 0 // + 14
-13/3*x = 14 // : -13/3
x = 14/(-13/3)
x = -42/13
x = -42/13
