Answer:

x=-5, y=-2

Explanation:

6x+ 28 =y

5x-y=-23

Substitute 6x+28 in for y in the second equation

5 x-(6x+28)=-23

Distribute the negative sign

5x -6x-28 = -23

-x -28 = -23

Add 28 to each side

-x-28+28 = -23+28

-x = 5

Multiply by -1

x = -5

Now we need to solve for y

y = 6x+28

Substitute x=-5

y = 6(-5) + 28

y = -30+28

y = -2
