I'll help with the first one. Start by getting x by itself. To do that, take the first equation and subtract y from both sides.
x = 3 - y
Then take the second equation and substitute (3 - y) in for any x value. simplify to get the value of y. then plug in y to the first equation to get the value of x.
(1,2) is the first answer. Follow the same steps for the rest.
