Question

Is this correct? Solve using the multiplication principle
-6n < 30
= -6n/ -6 < 30/ -6 Divide by 6
= n+0 < -5 Simply
= n < - 5
Check: Using -5
-6n < 30
= -6(5) < 30
= -30 < 30

Answer 1

when dividing by a negative the sign flips
-6n < 30
divide by -6
n > -5

check - let n = -4

-6 * -4 = 24
24 < 30

Answer 2

you made an error in your check:
its -6(-5) = 30
which is not < 30
