I'm really terrible at doing this, could someone PLEASE EXPLAIN how you got your answer? Thanks :)
Graph each system and determine the number of solutions it has. If it has one solution, name it.
1.) 3+y= -3
3x+y= 3

since these are linear and not the same line and they are not parallel they will have one solution. In order to graph it is easier if we solve for y:
1.)
3+y= -3
y = -6
3x+y= 3
y= -3x+3

if you graph them and look at the point where they intersect you have found the answer. To me it looks like (3,-6)
Note: if they were parallel they would never intersect and have no solution, if they were the same line then they would intersect infinitely many times.
