Answer 2

Yes it does turns out to be 4. -3,4 is a solution of the given equation. :D

Answer 3

Hey there,

(-3,4) is in the form of (x,y). So 'x=-3' and 'y=4'. Simply plug these values into the equation and see if the left side equals the right side. If it does, then it is a solution.

Answer 4

5(-3) -2y = -23
2y = -15 - (-23)
2y=8
y=4

Answer 5

thank you
