For this..
\frac{n}{-3}+5 \ \textgreater \  \mathrm{Apply\:the\:fraction\:rule}:\ \frac{a}{-b}=-\frac{a}{b} \ \textgreater \  -\frac{n}{3}+5 \ \textgreater \  \frac{n}{3}+5\ \textgreater \ 4

\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides} \ \textgreater \ -\frac{n}{3}+5-5\ \textgreater \ 4-5 \ \textgreater \ \ \textgreater \  -\frac{n}{3}\ \textgreater \ -1

\mathrm{Multiply\:both\:sides\:by\:}3 \ \textgreater \  3\left(-\frac{n}{3}\right)\ \textgreater \ 3\left(-1\right) \ \textgreater \  \mathrm{Simplify} \ \textgreater \  -n\ \textgreater \ -3

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}
\left(-n\right)\left(-1\right)\ \textless \ \left(-3\right)\left(-1\right) \ \textgreater \ \ \textgreater \  \mathrm{Simplify} \ \textgreater \  n\ \textless \ 3

Hope this helps!

In the accompanying diagram of parallelogram ABCD,diagonals AC and DB intersect at E, AE = 3x - 4, andEC = x + 12.What is the va
skelet666 [1.2K]

x = 8

Explanation:

AE = 3x - 4

EC = x + 12

SInce diagonals AC and DB intersect at E

it means the lines which meet at the intersection E are equal. A and C meet at E which gives AE and EC

AE = EC

3x - 4 = x + 12

collect like terms:

3x - x = 12 + 4

2x = 16

divide both sides by 2:

2x/2 = 16/2

x = 8
