Answer:

n<-8

Explanation:

-Look at the attached image for an easier follow along

-Start by multiplying 7 by n and 14, and your new equation will be

7n+ 98-5<12n+53

-Subtract 5 from 98

7n+93<12n+53

-Transfer like terms to either side, so by using inverse operations, subtract 7n and 53 from both sides

40<-5n

-At this point, you want to isolate the variable, n, and to do this you divide both sides by -5, giving you

-8<n

-BUT when dividing an inequality by a negative, you flip the inequality sign, so your answer will be

-8>n

-Typically, you want the variable on the left side, so just turn it,

n<-8
