Answer:
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
Answer:
(x + 3)·3 = x + 19 --> x = 5
