Step 1 - mulitply both sides by five:
x=10 + 5x/3
Step 2 - subtract 10 from both sides:
x-10 = 5x/3
Step 3 - subtract x from both sides:
-10 = 5x/3 - x
Step 4 - put both terms on the right over a common denominator:
-10 = (5x-3x)/3
Step 5 - Simplify the term on the right:
-10 = 2x/3
Step 6 - multiply both sides by 3/2:
-15 = x
To check the answer, substitute x = -15 back into the original equation and simplify:
Does -15/5 = 2+ (-15/3)?
Does -3 = 2+ (-5)?
Yes, -3 = -3
Therefore the answer is x= -15

You need to gather the terms that look alike on one side and the others on the other. Keep in mind that the sign changes from + to - or from - to + as you switch a term to the other side of the equal sign. Then you use the fraction rules to give all the terms on one side the same denominator. Then you'll be able to add and divide accordingly.
The answer should be : -15
