Question 414514
Is (1,5) a solution of the system?
5x - 2y = -5
3x - 7y = -32


Substitute (1 in for x) and (5 in for y) into both equations.
If you get a true statement, then it is a solution for that equation.


5(1) - 2(5) = -5
5 - 10 = -5
-5 = -5
- works in first equation


3(1) - 7(5) = -32
3 - 35 = -32
-32 = -32
- works in second equation


Both equations yield true statements when you substitute in,
therefore it is a solution of the system.
