Question

3-n/2=3/4 It's a fractional coefficient, and i keep getting -3/2 yet that's not the right answer apparently, not sure if I'm doing it wrong or not.

Answer 1

(3-n)/2 or 3 - (n/2) ??

Answer 2

\[\frac{3-n}{2}=\frac{3}{4}\]
\[\frac{4(3-n)}{2}=\frac{4(3)}{4}\]
\[2(3-n)=3\]
\[6-2n=3\]
\[-2n=-3~:~n=\frac32\]
or ......

Answer 3

\[3-\frac{n}{2}=\frac{3}{4}\]
\[4(3)-\frac{4n}{2}=\frac{4(3)}{4}\]
\[12-2n=3\]
\[-2n=-9~:~n=\frac92\]

Answer 4

Thanks
