elimination method

anonymous · Answer

sum both side, what you get..

anonymous · Answer

I agree. Use elimination. If you just add the two equation together, the -5y and +5y cancel out and leaves you with only xs.

anonymous · Answer

So you'd have -13x = -13 so x = 1

anonymous · Answer

but why do u chose elimination

anonymous · Answer

Because it's quick and easy and gets rid of the ys straight away so you can quickly solve for x.

ok now can you help me go step by step with the rest?
