Yes.
-4(3+n)=-12-4n>-32
multiply everything by (-1) and change the direction of the inequality
4n+12<32
4n<20
n<5
Try 0 in the original. It should work
-4(3)>-32
-12>-32 true.
Try 6. It should not work
-4(9)>-32, -36>-32, false.

.....first, do multiplication on the left side, recall the rule: if you multiply negative number by positive number, product will be negative number
..........since all terms are negative, both sides multiply by to get positive terms
..... but recall that > will change to <
...solve for
