Please rephrase your question using letters and grammar.

Then find the correct sub-forum for this post.

THEN you can get a value for x from your first equation (divide it by 2) then feed it in as x in the second equation. Rearrange and solve. Then put in the value you get for y into the first equation to get x.

Edit - Thanks Curly, now I look like (Edit - more of) a fool.

Just to start you off case_fee..

you take 2x = 4y - 14, divide by 2 to get x = 2y - 7, then you can substitute this for x into your other equation to give you an equation with just y.

Once you have y, x should be easy to find.
