Please Help Me With This Math Problem If I Get The Anser In A Explained Way I Can Solve The Rest class=

Answer :

Half of a number n

n/2

How far is n/2 from 14

l 14 - n/2 l

At most 5 units ( less or equal)

l 14 - n/2 l ≤ 5

Solve;

14 - n/2 ≤ 5

14-5 ≤ n/2

9 ≤ n/2

9*2 ≤ n

18 ≤ n

-(14-n/2) ≤ 5

-14+n/2 ≤ 5

n/2 ≤ 5+14

n/2 ≤ 19

n ≤ 19*2

n ≤ 38

Solution:

18 ≤ n ≤ 38
