### Formula for equation

You were right about that integral(my brother didn't knnw the solution either,but now he has given me another problem-

make a formula using a and b for x and y.

### Re: Formula for equation

When the two sides are added together, the left hand side turns out to be (x-y)^3. From there you can get:

.

Can you continue from here?

### Re: Formula for equation

Well,even if i find

i will need x and y so that they follow those 2 equation.

### Re: Formula for equation

Well, you can say that

and then substitute that into the second equation you are given. Then you can get y.
