Answer:
C
Step-by-step explanation:
Given the 2 equations
3y = x - 2 → (1)
y = - 2x + 4 → (2)
Substitute y = - 2x + 4 into (1)
3(- 2x + 4) = x - 2, that is
- 6x + 12 = x - 2 ( subtract x from both sides )
- 7x + 12 = - 2 ( subtract 12 from both sides )
- 7x = - 14 ( divide both sides by - 7 )
x = 2
Substitute x = 2 into (2) for corresponding value of y
y = - 2(2) + 4 = - 4 + 4 = 0
Thus x = 2 : y = 0 → C
