What is the solution of - 8/2y-8=5/y+4-7y+8/y2-16

- 4 y3 - 8 y2 = - 7 y3 - 12 y2 + 5y + 8 - 4 y3 - 8 y2 - ( - 7 y3 - 12 y2 + 5y + 8) = - 7 y3 - 12 y2 + 5y + 8 - ( - 7 y3 - 12 y2 + 5y + 8) (Subtract - 7y^3-12y^2+5y+8 from both sides) 3 y3 + 4 y2 - 5y - 8 = 0 (Use cubic formula) y=1.353543 Check answers. (Plug them in to make sure they work.) y=1.353543 (Works in original equation) Answer: y=1.353543

The answer would be - 0.102564 repeating because if you do the math before dividing you would get - 8/6.5/-1.5/-8
