I am also confused since you said "these problem." I am not sure if it's many (these) or one (problem).

My assumption is you have 2 equations:

Y+2x = 3 and

Y+2x = -4

Do you have to take these 2 and find out what x and y equal?

Ok so let me start over. System of equation can be solved by graphing, substitution or elmination method. I only have to choose one method and I was trying the elimination method is that how my problem seems to be?
