Let the tens digit be T. Then the units digit is T + 4.

Therefore, the number is 10(T) + (T + 4), or 10T + T + 4 = 11T + 4.

Since the number is 3 less than 4 times the sum of the digits, then we will have:

(11T + 4) + 3 = 4(T + T + 4), or 11T + 7 = 8T + 16

3T = 9

T = 3

The tens digit is 3, and the units digit is 7 (3 + 4). The number is then highlight_green%2837%29, or, 11T + 4 = 33 + 4 = highlight_green%2837%29.
