SOLUTION: Tell whether the ordered pair (5, �2) is a solution of the system x + y = 3 -2x + 2y = -14 Tell whether the ordered pair (5, �3) is a solution of the system -3x + 2y = -21

Question 1035605: Tell whether the ordered pair (5, �2) is a solution of the system
x + y = 3
-2x + 2y = -14
Tell whether the ordered pair (5, �3) is a solution of the system
-3x + 2y = -21
-x - y = -2

Tell whether the ordered pair (5,�2) is a solution of the system
x + y = 3
-2x + 2y = -14
---------------------
Sub 5 for x, and -2 for y in both equations.
If the = is true, it's a solution.
----------
Tell whether the ordered pair (5,�3) is a solution of the system
-3x + 2y = -21
-x - y = -2.
----
Same as above.
