x in (-oo:+oo)
(5*(x+3))/2-((7*x)/3) = (4*(x+8))/5 // - (4*(x+8))/5
(5*(x+3))/2-((4*(x+8))/5)-((7*x)/3) = 0
(5*(x+3))/2+(-4/5)*(x+8)+(-7/3)*x = 0
(5*(x+3))/2-4/5*(x+8)+(-7*x)/3 = 0
(3*5*(x+3))/(2*3)+(-4/5*2*3*(x+8))/(2*3)+(-7*2*x)/(2*3) = 0
3*5*(x+3)-4/5*2*3*(x+8)-7*2*x = 0
51/5*x-14*x+33/5 = 0
33/5-19/5*x = 0
(33/5-19/5*x)/(2*3) = 0
(33/5-19/5*x)/(2*3) = 0 // * 2*3
33/5-19/5*x = 0
33/5-19/5*x = 0 // - 33/5
-19/5*x = -33/5 // : -19/5
x = -33/5/(-19/5)
x = 33/19
x = 33/19
