Answer:
x = 4 , y = 0
Explanation:
y = - 2x + 8 → (1)
y = x - 4 → (2)
since both equations express y in terms of x , equate the right sides
x - 4 = - 2x + 8 ( add 2x to both sides )
3x - 4 = 8 ( add 4 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations and evaluate for y
substituting into (2)
y = 4 - 4 = 0
