Question 62285: If I might ask a second question (I apologize, I'm stuck; this is also from my teacher):
-3/7z = 7/5
I multiplied both sides by -7/1 and got 3z = -49/5, but am having trouble when I check my work.
Thanks again in advance.

%28-3%2F7%29z=7%2F5
%28-7%2F3%29%28-3%2F7%29z=%28-7%2F3%29%287%2F5%29
%2821%2F21%29z=-49%2F15
1z=-49%2F15
highlight%28z=-49%2F15%29
Check:
%28-3%2F7%29%28-49%2F15%29=7%2F5
%28-3%2F7%29%28%28-7%2A7%29%2F%285%2A3%29%29=7%2F5
%28cross%28-3%29%2Fcross%287%29%29%28cross%28-7%29%2A7%2F%285%2Across%283%29%29%29
7%2F5=7%2F5 We're right.
Happy Calculating!!!
