Yes, just substitute in both equations
1st:
Left Side = 2x-3 = 2(-3) - 3 = -9
but RS = 6, so the values don't even work in the first equation, you can stop here
(-3,4) is NOT a solution
I have a feeling that your first equation should have been
2x - 3y = 6
in that case:
LS - 2(-3) - 3(4) = -6
RS = +6
No point even trying the second
So no good either.
Yes, sorry Reiny I had forgotton the Y. And thanks for the explanation:)
