How may I help? (-:

I believe there are only two methods that can be put into consideration at this problem. One is substitution, meaning you express one variable in respect of the other and/or elimination, which means that you're trying to 'eliminate' one variable.

I, personally, would use substitution (-: Fortunately there is no right or wrong here.

(x+y) - (x-3y) =9 - (-3) <- Can you solve it?

anonymous · Answer

nooo

callisto · Answer

Consider the left side, 
(x+y) - (x-3y) 
= x + y - x + 3y
= ...?

callisto · Answer

Blah.... Is the question 'which method would you use to solve the equations' or 'solve the questions'?
