Question

tell whether the ordered pair is a solution of the linear system. (-4,-6); -3x+y=6, -2x+y=-8

Answer 1

plug them in... -4=x -5=y

-3x-4+-6=6 (check)
-3x-4=12-6=6 (ordered pair works with this equation)

-2x-4+-6=-8 (check)
-2x-4=8-6=2 (ordered pair does not work with this equation)

Therefore the ordered pair IS NOT the solution.

Hope this helps :)
