Question 1205753
-------------------
Solve -3x+5y=21 
------------------


Nothing appears wrong with it needing to be solved.


----------------
and 6x-y=-15
----------------


That one looks good too.



{{{system(-3x+5y=21,6x-y=-15)}}} AS A SYSTEM,


{{{system(y=6x+15,-3x+5y=21)}}}


{{{-3x+5(6x+15)=21}}}


{{{-3x+30x+75=21}}}


{{{27x=21-75}}}


{{{27x=-54}}}

{{{y=6x+15}}}
{{{y=-12+15}}}
