You are correct, y would equal -1 But let me show you why -5y+8=-3y+10 ---------------------------------------- Add 3y to each side -5y+8+3y=-3y+10+3y -2y+8=10 ------------------------------------------------ Subtract 8 on each side -2y+8-8=10-8 -2y=2 -------------------------------------------------------- Now divide each side by -2 -2y ÷ -2 = 2 ÷ -2 y = -1 ================================================================== Hope I helped, Have a great day! :D
