You can put this solution on YOUR website!
Plug in pair into both equations to determine if true or false.
Let x=-5, y=2
2%28-5%29%2B3%282%29=-4
-10%2B6=-4
-4=-4true
and test the other equation
%28-5%29-4%282%29=-10
-5-8=-10
-13=-10false
Since one equation tested false the pair is not a solution of the system.
