Let first number = x, second number = y and third number = z
1) y = x + 5
2) z = 4x
3) x + y + z = 323
Substitute y and z in equation #3:
x + x + 5 + 4x = 323
6x + 5 = 323
6x = 318
x = 53
Substitute x in equation #1:
y = 53 + 5
y = 58
Substitute x in equation #2:
z = 4(53)
z = 212
The numbers are: 53, 58 and 212.
