Answer: B. (3,1)

Step-by-step explanation:

The given system of linear equations :-

3x + y = 10......................(1)\\\\y = x - 2..................(2)

Substitute the value of y from equation (2) in equation (1), we get

3x + (x-2) = 10\\\\\Rightarrow\ 4x-2=10\\\\\Rightarrow\ 4x=12\\\\\Rightarrow\ x=3

Now, substitute the value of x in equation (2), we get

y=3-2=1

Hence, the solution of the given system of equation = (3,1)
