If you mean: 9y = 72 then y = 72/9 = 8
Without an equality sign it is not a straight line equation but if you mean 9y-12x-72 = 0 then y = 4/3x+8
57+9y=81y+12 45=72y 45/72=y
This statement is already nearly factored. The best we can do is pull out the 9 from each term:9x + 9y + 72 = 9(x + y + 8)
x2 - 81y2 = (x + 9y) (x - 9y)The actual numerical value depends on the values of 'x' and 'y'.
It is an equation and the value of y is 1
If you want the y-intercept, then you want the value of y when x=0 so3*0 - 9y = -27-9y = -27y = 3If you want the x-intercept, then you want the value of x when y=0 so3x - 9*0 = -273x = -27x = -9
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
y^2+9y-52 = (y+13)(y-4)
9y = 12.6 y = 1.4

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)
Y-8x plus 9y equals 10y-8x.
