I would begin by causing each term to have the same denominator.
This will change up some of the numerators. Show us some steps so we can help you catch the problem.
For this problem, you have to get all of the denominators to be the same, so you have to multiply each equation by a specific number so that each denominator will have a most common multiple. In this case, I think it is safe to say that the common denominator should be 36, meaning that the equation should be this after simplification:
Now just solve for x...
Hope this is right, but the equation did not come out really clear on my computer, but I hope I helped
