solve by the elimination method 5u+3v=-17, 2u+v=-7 would there be a solution or not?
Answered by Steve
since the lines have different slopes, they must intersect at a point somewhere.

5u+3v = -17
6u+3v = -21

now subtract one from the other to make the v's go away, and solve for u.

Then plug u back in to get v.
