Answer:
x=2 y,=3
(2,3)
Step-by-step explanation:
3x - 5y = -9
x + 2y = 8
We will use elimination. Multiply the second equation by -3
-3(x + 2y) = 8*-3
-3x -6y = -24
Add this to the first equation
3x - 5y = -9
-3x -6y = -24
-----------------------
0 - 11y = -33
Divide each side by -11
-11y/-11 = -33/-11
y =3
Now substitute into the second equation to find x
x+ 2y = 8
x+2(3) =8
x+6 =8
Subtract 6 from each side
x+6-6=8-6
x=2
Answer: 3x-5y=-9 is simplified to y=3/5x+9/5
x+2y=8 is simplified to y=-1/2x+4
