The answer to the problem at the very bottom is -3.08=z

-5 / -3 = 9 + 2.4z - 9 1.6 - 9 = 9 + 2.4z - 9 -7.4 / 2.4 = 2.4z / 2.4 -3.08 = z

sorry, actually the answer is correct but formula is this = [-5 / -3 = 9 + 2.4z - 9], [1.6 - 9 = 9 + 2.4z - 9], [-7.4 / 2.4 = 2.4z / 2.4], [-3.08 = z], i closed each part in so you can see it.

Wolfram Alpha gives a different answer (z=-3.47826) than either the above or the original page. Hmm... yet when I paste the original in as written (here), I get approximately the same answer as on the original page (z=-1.96429)
