Answer 6

Yes

Answer 7

ok well then it shouldn't be that bad:

the first thing we want to do it get anything with an "a" in it together. so we would do:

3/a= [(1/c) -(2/b)]
The reason i put it in brackets is so that we traet the tire thing as one piece. then we do some cross multiplication and division:

3= [(1/c) -(2/b)]*a

3/[(1/c) -(2/b)] = a

Answer 8

This also can be simplified to get
\[ a=\frac{3 b c}{b-2 c}
\]
