Answer:

Option A is correct

Step-by-step explanation:

Given two equations

x-y=2....(1)

2x+3y =14...(2)

we have to solve the above equations using elimination method.

Multiplying (1) equation by 2, we get

2x-2y=4....(3)

Subtract equation (3) from (2), we get

3y-(-2y)=14-4

5y=10

Dividing by 5, we get

y=\frac{10}{5}=2

(1) implies x-y=2

x-2=2

x=2+2=4

hence, the solution is (4,2)

Option A is correct.
