Answer:

B

Step-by-step explanation:

Given the 2 equations

x - 2y = 3 → (1)

2x - 3y = 9 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x

- 2x + 4y = - 6 → (3)

Add (2) and (3) term by term to eliminate x, that is

y = 3

Substitute y = 3 into either of the 2 equations and solve for x

Substituting into (1)

x - 2(3) = 3

x - 6 = 3 ( add 6 to both sides )

x = 9

Solution is (9, 3 ) → B
