How do you solve #x+3=2x-5#?
x = 8
You want to isolate the "x" on one side, so subtract "x" from one side and move it over to the other side with "2x."
3 = 2x - x - 5
Then move the -5 to the other side by changing the sign (-5 to +5) and adding it to the other side.
3 + 5 = 2x - x
Solve it and you should result with 8 = x.
