Question 1055735
Use the number properties that you have been learning; only one small change, to watch for any multiplication by negative number.


{{{-3p+21>21}}}
{{{-3p>21-21}}}
{{{-3p>0}}}
{{{-3p(-1)<0(-1)}}}--------this is the only step that is different than for equations.
{{{p<0}}}



Here is an alternative way:
{{{-3(p-7)>21}}}
{{{0>3(p-7)+21}}}
{{{0>3p-21+21}}}
{{{0>3p}}}
{{{0/3>3p/3}}}
{{{0>p}}}------------which is the same thing, but just turned around according to symmetric property which seems to be meaningful here.
