Question

how do the steps of -4(3+n)>-32
-3(r-4)lessequal to 0
-132>12(N+9)
-90lessequal to -5(K-3)
can anyone please help me I don't understand it

Answer 1

-4(3+n)>-32
distribute the -4
-12 -4n > -32
add 12 to both sides
-4n > -20
divide both sides by -4
n < 5

(when dividing by a negative in an inequality you nee to flip the inequality sign)

Answer 2

the rules are the same as for equations except for the 'flip' rule
