23 3*(4*x - 5) 17*x 3*(3*x - 7) 2*x - 78/5 - -- - ----------- + ---- = ----------- + ---------- 5 2 2 10 7
-(23/5)-(3/2)*(4*x-5)+(17/2)*x = (3/10)*(3*x-7)+(2*x-(78/5))/7
-23/5-3/24*x-5+17/2x = (3/10)*(3*x-7)+(2*x-(78/5))/7
-23/5-3/24*x-5+17/2x = 3/103*x-7+2*x+78/5)/7
29/10 + 5*x/2 = 3/103*x-7+2*x+78/5)/7
29/10 + 5*x/2 = -303/70 + 83*x/70
x = -253/35 / (46/35)
