Substitution question? (Algebra 2)?

Part of my homework is asking me to check whether the ordered pair is a solution of the system.

For this example:

(-3, 5)

3x-7y= -34

-5x-2y= 5

I did the work, assuming I did it right... I plugged in the ordered pair numbers where X and Y are in the systems. It's asking if the ordered pair is a solution. Well, the first system did not equal out and the second one did. What does that mean?

(Meaning, I got this as my answer: - 44 = - 34 and 5 = 5)

    You did it right. The ordered pair is not part of the system solution. For an ordered pair to be a solution to the system it has to be correct for all equations in the system.

    The ordered pair (-3,5) is one solution to the second equation, but it is not a solution to the system.
