4x-y=8
-4x (subtract -4x from both sides)
-Y=-4x+8
/-y (divide -1y from both sides)
Y=4x-8
answer is: y=4x-8
(4,1)
<span>Set the two equations equal to each other and solve for x
10x +50 = 8x +60
-50 -50
-----------------
10x = 8x + 10
10x = 8x + 10
-8x -8x
---------------
2x = 10
2x = 10
divide by 2 on both sides
x=5
