You can put this solution on YOUR website! decide whether an ordered pair is a solution of a linear system
(-5,-3)
4x+y=-23
2x+4y=-22
-----------
Sub -5 for x and -3 for y, see if it's equal.
You can put this solution on YOUR website! Yes this ordered pair is a solution
to the linear system.
4x+y=-23
2x+4y=-22
substitute the x and y values
in the equations
4(-5) + (-3) = -23
-20 + -3 = -23
-23 = -23 Correct
2(-5) + 4(-3) = -22
-10 + -12 = -22
-22 = -22 Correct.
Hope this helps.
