You can only simplify, and by the way you wrote it, it is a bit confusing. I'll assume you mean: 8y + 2 - 18y -5. In order to do this you must combine like terms, or the same things. We can combine 8y and -18y, as they are both y. 8y - 18y = -10y. Now we can combine 2 and -5, as they both are plain. 2 - 5 = -3. Your final answer would be: -10y - 3.

-8y+9=18y-4Add 8y to both sides.9=26y-4Add 4 to both sides.13=26yDivide 13 by 26.1/2=y or 0.5=y

10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....

8(y - 1)(y^2 + y + 1)

If: -8y-7 = -8+8y Then: -7+8 = 8y+8y And: 16y = 1 So: y = 1/16

Not sure which you mean, take your pick: (8y)3+27=(8y+3)((8y)2-3*(8y)+9)=(8y+3)(64y2-24y+9); or 8y3+27=(2y+3)(4y2-6y+9)
