Let x be the number.
and (x-17) is the other number lesser than that number:

x + (x-17) = 125
x + x - 17 = 125
2x - 17 = 125
*transpose -17 to the right side of the equation becomes,
2x = 125 + 17
2x = 142
*Divide both sides of the equation by 2 to find x.
2x/2 =142/2
X=71
*Substitute 71 to (x-17) to find the other number because the question says that the one number is 17 less than the other.

(x-17)
71 - 17 = 54
Therefore: x-17 is equals 54

FINAL ANSWER: The number are 71 and 54. Their sum is 125

To check, SUBSTITUTE the VALUE OF "x" in the equation and check their sum:
X=71

x + (x-17) = 125
71 + 71 - 17 = 125
125 = 125

Also check if one number is 17 less than the other:

71 - 54 = 17

So therefore 71 and 54 are the numbers. :)
