Hey everyone I am having a problem with something. We were learning about systems and substitution equations and how to solve them today and I am not really understanding where they are going with this. I am given the two equations but I am not sure what I am supposed to do from there? There were a few other equations on here that I was able to do but these ones are formatted different so can you please help explain these to me if possible? Thank you.

X + 3Y = 6

4X - 2Y = 10

and

5X + Y = 11

10X + 2Y = 20

I was looking at some other threads in here but everything seems so confusing; these two were formatted differently from the ones I read. Any help is appreciate, thanks.
