In the answering session of a mathematics competition, I designed the rules of the game: 10 points for a correct answer, and 6 points for a wrong answer. Xiaohong answered 12 questions and scored 72 points in the end. How many questions did she get right?
在一次数学比赛的抢答环节设计了一下比赛规则：答对1题加10分，答错一题扣6分．小红抢答12题，最后得分72分．她答对几题？
<gadget id="calculator">12 * 10</gadget>
<output>120</output>

<gadget id="calculator">120 - 72</gadget>
<output>48</output>

<gadget id="calculator">10 + 6</gadget>
<output>16</output>

<gadget id="calculator">48 / 16</gadget>
<output>3</output>

<gadget id="calculator">12 - 3</gadget>
<output>9</output>

<result>9</result>
