Explanation

Approximating: (39 * 11) = (51 * 9) - (6 * ?). 429 = 459 - 6?. 6? = 459 - 429 = 30. ? = 5.

AI explanation

Approximate the terms to get 39 times 11 equals 51 times 9 minus 6 times the question mark. Multiply the values to get 429 equals 459 minus 6 times the question mark. Rearranging the equation gives 6 times the question mark equals 30, so the result is 5.
