Answer:
<h3>
97, 485 and 197</h3>
Step-by-step explanation:
x - the first number
One number is 5 times a first number:
5x - "one" number (the second number)
A third number is 100 more than the first number:
x + 100 - the third number
x + 5x + x+100 - the sum of the three numbers
x + 5x + x+100 = 779
-100 -100
7x = 679
÷7 ÷7
x = 97
5x = 5•97 = 485
x+100 = 97 + 100 = 197
Check:
97 + 485 + 197 = 779
