There is one solution. The solution of the system is (9,-5)
Option A is correct.
Step-by-step explanation:
We need to solve the system of equations by elimination method

Rearranging the equations:

Eliminating y to find value of x:
Multiply eq(1) by 5 and eq(2) by 2 and add both equations:

So, value of x= 9
Eliminating x to find value of y:
Multiply eq(1) by 2 and eq(2) by 6 and subtract both equations:

So, value of y = -5
