x=3x-5 Start with the given equation



x-3x=-5 Subtract 3x from both sides


-2x=-5 Combine like terms on the left side


x=%28-5%29%2F%28-2%29 Divide both sides by -2 to isolate x



x=5%2F2 Reduce

--------------------------------------------------------------
Answer:
So our answer is x=5%2F2 (which is x=2.5 in decimal form)
