I've looked everywhere to try and solve this formula and I know it must be simple for others, so I'm hoping someone here can help me. I'm not even sure if it's algebra or some other kind of math and there may be more than one answer.

I'm looking for a formula that will tell me every combination for what X and y have to represent for the formula 1000=x+(y*1.5) to be correct

For example, I know right off the bat that the formula would be correct if x=250 and y=500 but how can I determine with a formula what combinations for X & Y in the above formula will equal 1000 exactly? If there is more than one answer, would an "if" formula in Excel be better (but I don't know how to create that formual)

If there is an excel formula for this, that would be even better.

Thank you all!
