multiple-choice question
do you have to check the ordered pair for the second equation?
yes
no

Explanation:

To determine if an ordered pair is a solution to a system of equations, it must satisfy all equations in the system. Even if it works for one equation, we need to check the second (and any other) equation to confirm it's a solution for the entire system.

Answer:

Yes
