-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'.

The GCF is 9y^2.
Oh, dude, that's like asking me to solve a math problem at a party. So, the expression "8 less than the product of y and 9" is just y times 9 minus 8. It's as simple as trying to find your friend's lost phone after a night out - a little annoying but not too complicated.
To simplify this expression, you combine your like terms (9y and 1y). 9y - 1y = 8y 8y - 25 is your answer. It can't be simplified any further than that.
To find the addictive inverse of (9y), you need to determine the value that, when added to (9y), results in zero. The addictive inverse is simply (-9y). Thus, the addictive inverse of (9y) is (-9y).
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
x + y = 16 so x = 16 - y 10y + x = 10x + y - 18 9y = 9x - 18 ie 9y = 144 - 9y - 18 ie 18y = 126: y = 7 so original number was 79
All sides of a rhombus are the same length. So x + 9 = 50 so that x = 41 Also, 9y + 5 = 50 so that 9y = 45 and therefore y = 5
2y-5=11y+40 Subtract 2y from both sides -5=9y+40 Subtract 40 from both sides. -45=9y Divide by 9. -5=y
