Question 1180819
<pre>
Eq. 1        x-y=-m
Eq. 2       2x+y=m-1
Eq. 3        x+5y=4m+1
</pre>

{{{system(x-y=-m,2x+y=m-1,x+5y=4m+1)}}}


{{{system(x-y+m=0,2x+y-m=-1,x+5y-4m=1)}}}


{{{system(x-y+m=0,0+3y-3m=-1,0+6y-5m=1)}}}


{{{system(x-y+m=0,3y-3m=-1,0+m=3)}}}
and continue to find y and x, using the found value of m.















reworked, fixed mistake
