I wasted my time in school learning math from incompetent teachers.
I wish you were my teacher.
You are exceptionally gifted.

OMG FINALLLY. i need a why, not just a how. What is the point of just how. Mabey math wouldn't be such a teeth pull if teachers explained why.

can you choose which ever method of solving systems you want ? or would different equations need to be solved differently ?

I would have just added the first two lines and get y.
