It would be x = 18
You can get this by adding/subtracting common values. If you get all the x values on one side and all constants on the other side, you end up with
2x = 36
and all you have to do is divide by 2 to get x = 18.
Answer:
move the numbers with 'x' to the left side and the ones without 'x' to the right side.
8x - 7x + x = 28 + 8
x = 18
hope this helps :)
