13 less than half a number is five. Find the number

Answer 1

13 less than:

This means we are going to take 13 away from.. SUBTRACT 13:  - 13

 

half a number:  n/2  or  (1/2)n

 

is five:  = 5

 

Your equation is:

n/2 - 13 = 5

 

add 13 to both sides

 

n/2 = 18

 

multiply both sides by 2

 

n = 36
