Let one of the numbers be x.
The other number is 14 less than twice the other:
Twice the number = 2x
14 less than twice =2x - 14
So one of the number is x, and the other is 2x - 14
Since the sum is 67.
x + 2x - 14 = 67
3x - 14 = 67
3x = 67 + 14
3x = 81
x = 81/3
x = 27
Recall the two numbers are, x and 2x - 14
x = 27
2x - 14 = 2*27 - 14 = 54 - 14 = 40
So the two numbers are
27
and
40
.
Hope this helps.

Let, first number = x
Second number = 2x - 14
It is given that, x+2x-14 = 67
3x = 67+14
x = 81/3
x = 27
Also, (2x-14) = 2(27)-14 = 54-14 = 40
In short, Your Numbers would be 27 and 40
Hope this helps!
