x in (-oo:+oo)
(5*x)/2-((x-3)/7) = (x+5)/3 // - (x+5)/3
(5*x)/2-((x-3)/7)-((x+5)/3) = 0
(-1*(x-3))/7+(-1*(x+5))/3+(5*x)/2 = 0
(-1*2*3*(x-3))/(2*3*7)+(-1*2*7*(x+5))/(2*3*7)+(3*5*7*x)/(2*3*7) = 0
3*5*7*x-1*2*3*(x-3)-1*2*7*(x+5) = 0
105*x-20*x-52 = 0
85*x-52 = 0
(85*x-52)/(2*3*7) = 0
(85*x-52)/(2*3*7) = 0 // * 2*3*7
85*x-52 = 0
85*x-52 = 0 // + 52
85*x = 52 // : 85
x = 52/85
x = 52/85
