Hmm...linear combinations. Not sure which method that is, but I do know about substitution and elimination. In case you want those, do say. @ammar-93 , do explain the linear combinations.

Ithink we have to draw the first line and then draw the second , then the points they're atqatwa on it , it's the solves ... I'm not sure !

anonymous · Answer

i'm not familiar with the method term also but I think linear combination is elimination because you're multiplying a number to one or both equations (linear combination) to do elimination...

anonymous · Answer

of course, that's just my guess... :)

anonymous · Answer

Okay , I understand . But , It probably does mean elimination , this "new math" is confusing tho, :D

anonymous · Answer

try this... 
multiply the top equation by 3, multiply the bottom equation by 2, then add the resulting equations... you'll eliminate the x variable this way....

anonymous · Answer

After I add the resulting equations what do I do afterwards ?

allank · Answer

After doing the addition, you should have only one variable left (the other having being eliminated), then solve for that specific inequality. E.g. if you are left with 3x = 9, x=3.
