Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)
The above three expressions could be used to represent the numbers.
Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44
x = 11, y = 7, z = 44.

Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
1) x = 4
2) x = 12
3) x = 45
4) x= 5.56
5) x = 35/18
6) x = 3/2
7) x = 19/3
8) x = 3/35
9) x = 47/5
10) x+4 = 17/2 so x = 9/2
