As usual, this is much easier to do by elimination. There are other ways to practice your algebraic manipulation if that is what you want.

True — elimination is easier for this one, but since the goal is substitution practice, it’s the right method to use.

It’s mainly for practice. Using substitution here is a good exercise.

x=2;y=3

I did this in my head. It's trivial.
