Answer:
The three numbers are 17, 24 and 68.
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Sum of three numbers = 109
Second number is 4 times the third
First number is 7 more than the third
2. What are the numbers?
Let's prepare and write our equation to answer this question, this way:
x = Third number
4x = Second number (4 times the third)
x + 7 = First number (7 more than the third)
x + 4x + x + 7 = 109
6x = 109 - 7
6x = 102
x = 102/6
x = 17 ⇒ 4x = 68 ⇒ x + 7 = 24
The three numbers are 17, 24 and 68.
