we call : a, b - the numbers

a + b = 82 │ × 4
3a - 4b = 29

4a + 4b = 328
3a - 4b = 29 +
---------------------------
7a / = 357

7a = 357 a + b = 82

a = 357 : 7 51 + b = 82

a = 51 b = 31

The sum of two numbers is 82. three times the larger number minus four times the smaller number is 29. find the numbers
