3x + 8 = 17
Subtract 8 from both sides
3x + 8 - 8 = 17 - 8
Simplifying
3x = 9
Divide both sides by 3
3x/3 = 9/3
Simplifying
x = 3
Answer
x = 3
So find a common lets use 2 on the top
2x-4y=30
2x+4y=-18, now we have 4x=12, x=3
so lets substitute, lts use the top
3-2y=15
-2y=12
y=-6
im not sure x could be 12 i would try plugging each one them into the equation and see with one balances out
the other one is x=12, y=-3/2
