put this solution on YOUR website!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:

--> i take it, you meant this? rather than

?
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

You can
put this solution on YOUR website!There is really nothing to solve here!
You have an algebraic expression

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:

Apply the distributive property.
