your stuck!? apparently you cant do anything, but yea you should post one question of each that are similar, for the problem near the bottom,

2y+x=9 you would just plug in x for that equation then combine like terms

for the last one you can elimate the three to solve for it, then divide by 2

you probably should look up youtube videos for lessons help and examples

ok it truly is whatcha do. attempt to discover or trend some form of lever utilising a stick or something similar. then you truly slip it behind your again between your a** cheeks. Use the rock (or demanding position whichever is behind you) for leverage. Then push down on the bar, and it is going to pop you good out. If that fails do exactly what Winnie the Pooh did and wait some days until eventually you skinny out and also you should shimmy out. sturdy success. let me comprehend the way it is going.

holy crap. nobody is going to do your whole paper. Try asking one question at a time, or maybe try paying attention in class.
