Answer :
make them equal to eachother to solve for x
-2x + 8 = x - 4
add 2x to both sides and 4 to both sides.
12 = 3x
divide by 3 to solve for x
x = 4
Now substitute 4 in for x to solve for y
y = (4) - 4
y = 0
Solution is:
x = 4, y = 0 or
(4,0)
-2x + 8 = x - 4
add 2x to both sides and 4 to both sides.
12 = 3x
divide by 3 to solve for x
x = 4
Now substitute 4 in for x to solve for y
y = (4) - 4
y = 0
Solution is:
x = 4, y = 0 or
(4,0)
