wow i guess it is too much to ask just how to solve it. 
must be some on line class, perhaps FLVS
if you multiply the second equation by $-3$ you get $$-14x+9y=21$$ and then add the $y$ terms will drop out

no wonder you suck at math, this is not a math question, this is a math teacher question
the math question would be "solve the system"
