The sum of 3 less than 5 times a number and and the number increased by 9 is 24. What is the number?

Answer 1

Eva Abramson

The number is 3

Let #x# be the unknown number

"3 less than 5 times a number" --> #5x-3#

"number increased by 9" --> #x+9#

The sum of 24 #5x-3+x+9=24# #6x+6=24# #6x=18# #x=3#

Therefore, the number is 3
