First we pick the equation. Let's say we pick first one. From it we express y.

Then we use this y and plug it in instead of y in the second equation.

Now just solve for x.

We plug this x in the first equation.

And solve for y.

So the solution to the equation is geometrically a point P which lies on the intersection of the two lines.

Hope this helps.
