-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
-9y-15x ---- -3
9y - 4x
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.

9y - 9 = -117 9y - 9 + 9 = -117 + 9 9y = -108 9y/9 = -108/9 y= -12
-9y + 8 = -91-9y = -91 -8-9y = -99y = -99-----9y = 11-99/-9 = 11 because -9X11 = -99
314-9y = 305
9y-3 = 6
-9y-15x ---- -3
9y - 4x
9y-11=7 +11 +11 9y=18 y=2
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
4x2 - 9y Not factorable from what I see.

Yes, 6 and 9y are unlike terms. The 6 is a constant and 9y is constant attached to a variable.
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
