9y + 5 = 0 (-5 on both sides)9y = -5 (/9 on both sides)y = -5/9
What is 31 equals 4-9y?
y = 3 in the equation 31 = 4 - 9y Solve for y. 31 - 4 = 4 - 9y - 4 Simplify 27 = 9y Divide both sides by 9 to get the term y by itself on one side of the equation. 27 / 9 = 9y / 9 Simplify 3 = y

3x-2y+9+9y-x = 2x+7y+9
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
What is the system of equations and enter the solution as an ordered pair 9x - 2y equals 73 5x - 9y equals 9?
(1) 9x-2y=73 (2) 5x-9y=9 from (1) 9x-2y+2y=73+2y => 9x= 73+2y => x = (73+2y)/9 put into (2) 5x-9y = 9 => 5(73+2y)/9 - 9y=9 => 10y/9 + 365/9 -9y = 9 => 10y/9 - 9y = 9 -365/9 = -284/9 => -71y/9 = -284/9 => 71y= 284 => y = 284/71 = 4 and x = (73+2*4) / 9 = 9
The product of y and 9?
9y
Factorise x2 minus y2 plus 9x minus 9y?
x2 - y2 + 9x - 9y =(x2 + 9x) - (y2 + 9y) =x(x + 9) - y(y + 9)================================Another way to go after it:x2 - y2 + 9x - 9y =(x2 - y2) + 9x - 9y =(x + y) (x - y) + 9 (x - y) =(x + y + 9) (x - y)
