Question 337625
Plug in the values and see if the equations are satisfied.
{{{2x + y = -1}}} 
{{{2(1)+(-3)=-1}}}
.
.
.
{{{3x + 2y = -3 }}}
{{{3(1)+2(-3)=-3}}}
.
.
.
Take it from there and see if the right and left hand sides match for each.
If they both do, then it's a good solution.
Else, it's not a solution.
