If you want me to solve for "Y" then, the answer will be,
ir if you want me to solve for "X" instead then the answer will be,
The answer is 7/5 th. You can add fractions without first having a common denominator so you would change the 8's by multiplying it by 5 to get 40 and you would multiply the 5 by 8 to get 40 as well. And the rule whatever you do to the bottom you have to do to the top so whatever you multiplied 8 by do the same for the numerator and whatever you multiplied 5 by you do the same for the numerator. So your new equation would be (75/40+16/40)+(-35/40). you would then add the numerator's across to get 56 and the denominator would stay the same so the answer is 56/40. But you have to now simplify 56/40 down to 14/10 and then once more to 7/5 which is the final answer.
15-2x=3x
Add 2x to both sides
15=5x
Divide by 5 on both sides
3=x
Hope it helps (:
Yes, they are all equal to each other
