Two math problems - Loses - May 9, 2017
I'm not sure what I am doing wrong and I can't seem to get help on it from my school..
So I thought I should ask y'all smarties

I end up with the wrong answer... Not really sure what to do for these, for the first one I factor out the u and then not sure what to do.
Thanks a lot

first one was wrong,ignore my stupidity.

The second one is a little too much work for me, so the first one is:
G = [x(y+z)]/a - Just factoring the x out of the two terms.
x(y+z) = G a - Cross multiplication.
x = (G a)/(y+z) - Dividing (y+z) on both sides.

Can't use equivalence symbol, c can be 0!!!!!!

I mean sure, c might be 0 but based on how it is in the denominator in the question and how this is clearly a high school question at the most, I think we can safely assume that the question did not intend to trick students by the case where c = 0. So you can use the equivalence symbol, not that you get a choice from the question.

I personally wouldve used it on the situation, but my old teacher used to be an asshat about its usage lol

Maybe but in the picture in the original post it is already given that x = or c =
