Hi;

You do not need to copy my posts. It is not necessary and it is extra work.

Take the first equation and solve for q^H. You get:

Shouldn't it be 3b-ub on the bottom ?

Hi;

No, we are not done yet. I just solved for q^H, it is not the final answer.

I know, but on the thing you posted, the denominator you got ub-3b and I have 3b-ub

You should notice that I have a q^L in the partial answer. That is because it is not done yet.

I know we are not done, but on the expression you just posted for qh.... at the bottom you have b(u-3) and I get b(3-u), this is what I am talking about.

You mean on the step I just did or on the final answer?
