right, well first you would not "solve" it, as it isn't equal to anything. Even if it was equal to something, you have 2 unknowns... x and y and just one equation.

If you meant, how do i expand the bracket? then what it actually is saying, written out fully, is:

-1x%2A%28%28%2B3%2F7%29%2B1y%29 --> i take it, you meant this? rather than 3%2F%287%2By%29?

so the (-1x) has to be multiplied to both the (+3/7) and the (+1y). These each give:

-(3x)/7
and
-xy

--> answer is -(3x)/7 - xy

There is really nothing to solve here!
You have an algebraic expression -x%283%2F7+%2B+y%29 and, unless you are given the values for x and y, you cannot evaluate it.
To "solve" this, it would have to be an "equation" in which the "expression" you have is equal (=) to something. But, no equals, no equation.
The only thing that you can do is to "simplify" this expression by applying the "distributive property".
Is this what you wanted?
Simplify:
-x%283%2F7+%2B+y%29 Apply the distributive property.
-3x%2F7+-+xy
