8y + 7y = 15y
So [ 8y + 9 + 7y ] = 15y + 9
If you want to get fancy and factor that expression, it's 3(5y + 3) .

7 + 8y - 3y + 2 =7 + 2 + 8y - 3y = 9 + 8y - 3y = 9 + 5y
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)
This simplifies to 6+13y If you meant 9+7y-(3+6y) then it becomes 6+y It is not clear from the problem which you meant.
-8x-9+(-18) -8x-9-18 -8x-27 is your simplified answer
It is: 11p+11 simplified
