Tao uses elimination to solve the following system of linear equations.

Given:

The system of equation is:

To find:

The solution of the given system of equations.

Solution:

We have,

             ...(i)

               ...(ii)

Add (i) and (ii) to eliminate the variable x.

Putting in (ii), we get

Divide both sides by 2.

Therefore, the solution of given system of equations is (0,4). Hence, the correct option is A.
