these are a couple of problems i can't figure out. i would appreciate any help.

x-y=120
x+y=150  ....That's one problem. You have to find the values of x & y , using the substitution method.

and the next one is   y=x-2  ... This one needs to be put into y-form, but i don't understand how to do that.
