x=5
3x+2-5x=5x-8-5x
-2x+2=-8
-subtract 2 from both side
-then you divide both sides by -2
(got lazy with it but the answer is x=5)

3x + 2 = 5x - 8
Flip
5x - 8 = 3x + 2
Subtract both sides by 3x
2x - 8 = 2
Add both sides by 8
2x = 10
Divide both sides by 2
x = 5
That's your answer.
Have an awesome day! :)
