Answer:
x=-5, y=-2
Step-by-step 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
