Answer:
27, 80, 20
Explanation:
Let t represent the third number. The second number is 4 times that, 4t. The first number is 7 more than the third, so is (t+7). The sum of the three numbers is ...
(t+7) + 4t + t = 127
6t +7 = 127 . . . . . . collect terms
6t = 120 . . . . . . . . .subtract 7
t = 20 . . . . . . . . . . . divide by 6; the 3rd number is 20
4t = 80 . . . . the second number is 80
t+7 = 27 . . . the first number is 27
The three numbers are 27, 80, and 20.
