-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
(5y - 2)(5y + 2)
x = 0 and y = 4
X = -2(13 + y) / 3x = 5y / 4 - 1
-2
(3y - 5)(y + 5)
Y=-1
It is: minus 1.25
what is the solution of x-5y=10 and 2x-10y=20
If: 2x+5y = 2 and -3x-y = -3Then it works out that: x = 1 and y = 0
4x-5y+20 = 0 -5y = -4x-20 y = 4/5x+4 which is now in slope intercept form
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
