If 3 is added to a number and the sum is tripled, the result is 19 more than the number. find the number

The number is 5

Step-by-step explanation:

if 3 is added to a number and the sum is tripled, the result is 19 more than the number

(n+3) *3 = n+19

Distribute the 3

3n +9 = n+19

Subtract n from each side

3n-n +9 = n-n+19

2n +9 = 19

Subtract 9 from each side

2n+9-9 = 19-9

2n =10

Divide by 2

2n/2 =10/2

n=5

The number is 5
