x in (-oo:+oo)
x/3-((2*(x-7))/5) = (4/3)*x // - (4/3)*x
x/3-((2*(x-7))/5)-((4/3)*x) = 0
(-2/5)*(x-7)+x/3+(-4/3)*x = 0
x/3-2/5*(x-7)+(-4*x)/3 = 0
(-2/5*3*(x-7))/3+x/3+(-4*x)/3 = 0
x-2/5*3*(x-7)-4*x = 0
42/5-1/5*x-4*x = 0
42/5-21/5*x = 0
(42/5-21/5*x)/3 = 0
(42/5-21/5*x)/3 = 0 // * 3
42/5-21/5*x = 0
42/5-21/5*x = 0 // - 42/5
-21/5*x = -42/5 // : -21/5
x = -42/5/(-21/5)
