    The correct answer of the problem is 1.

    Step-by-step explanation:

    Let the original number on which the wrong procedure is applied is x.

    Now, Steve multiplied by 7 and then added 3 to get the answer of - 11.

    So, 7x + 3 = - 11

    ⇒ 7x = - 14

    ⇒ x = - 2

    Now, the correct step to get the answer is multiplying by 3 and adding 7.

    Hence, the correct answer of the problem is ( - 2) * 3 + 7 = - 6 + 7 = 1 (Answer)
