Answer:
(6,3)
Step-by-step explanation:
2x + y = 15
x - y = 3
I will use elimination to solve the system. Add these equations together to eliminate y.
2x + y = 15
x - y = 3
-------------------
3x = 18
Divide by 3
3x/3 = 18/3
x =6
Now we need to find y
x-y =3
6-y =3
Subtract 6 from each side
6-6-y=3-6
-y=-3
Multiply by -1
y=3
