For this question, you should know how to equalize and solve quadratic equations.

There are 2-3 ways with which you can solve this question.

The easiest one is to arrange equation 2 in such a way that you get it in terms of y and put it in equation 1 in place of y.

This will give you the value of x. Then put this x in any of the equation to get value of y.

Then simply add x+y to get the value.
