Answer: (5,0)

Step-by-step explanation:

x - 3y =5 -----------(1)

2x + y = 10 ----------(2)

By elimination method, multiply eqn(1) by 2

2x - 6y = 10 ------------(3)

eqn(3) - eqn(2)

-7y = 0

Divide bothside by -7

y= 0

Now, we substitute the value of y in eqn(1)

x - 3(0) = 5

x - 0 = 5

x=5

Therefore,x=5 and y=0
