Answer:
(- 6, - 8 )
Step-by-step explanation:
Given the 2 equations
y = x - 2 → (1)
2x + 4 = y → (2)
Substitute 2x + 4 = y into (1)
2x + 4 = x - 2 ( subtract x from both sides )
x + 4 = - 2 ( subtract 4 from both sides )
x = - 6
Substitute x = - 6 into (1) for corresponding value of y
y = - 6 - 2 = - 8
Solution is (- 6, - 8 )
