First find x and y.
Solve system of equations by elimination.
3x-y=3
+(-x+y=3)
---------------
2x=6
x=3
Now plug in x into one of the equations to find y.
-3+y=3
y=6
xy=3x6=18
f(x) - g(x)
=> (3x² + x - 3) - (x² - 5x + 1)
=> 3x² + x - 3 - x² + 5x - 1
=> 3x² - x² + x + 5x - 3 - 1
=> 2x² + 6x - 4

Answer:
![\displaystyle [3, 5]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B3%2C%205%5D)
Step-by-step explanation:
{8x + 8y = 64
{y = x + 2
8x + 8[x + 2] = 64
8x + 8x + 16 = 64
16x + 16 = 64
- 16 - 16
