Answer:
A
Step-by-step explanation:
Given the 2 equations
3y = x - 1 → (1)
x - 2y = 2 → (2)
Rearrange (2) expressing x in terms of y by adding 2y to both sides
x = 2 + 2y → (3)
Substitute x = 2 + 2y into (1)
3y = 2 + 2y - 1 ( subtract 2y from both sides )
y = 2 - 1 = 1
Substitute y = 1 in (3) for corresponding value of x
x = 2 + (2 × 1) = 2 + 2 = 4
Solution is (4, 1)
