X+ 3y = 7 x - 3y = 1 solve the system of equations. a) x = 4, y = 1 b) x = 1, y = 4 c) x = - 2 3 , y = 3 d) x = 3, y = - 2 3

Option A.

Step-by-step explanation:

The given system of equations is

        ... (1)

       ...(2)

We need to solve the system of equations.

On adding equation (1) and (2), we get

Divide both sides by 2.

Substitute x=4 in equation (1).

Divide both sides by 3.

Since x=4 and y=1, therefore the correct option is A.
