Question 11978
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*((+3/7)+1y)}}} --> i take it, you meant this? rather than {{{3/(7+y)}}}?


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
