Answer:<em> 44 matches</em>
Step-by-step explanation:
<em>Let's take the given information</em>
<em>They won 37 matches</em>
<em>1/9th of their matches resulted in a draw</em>
<em>1/9 out of 90 is 9</em>
<em>You can take 90/9 and you will get 9</em>
<em>Now let us add 37+9 and you get 47</em>
<em>Now take 90-47</em>
<em>44 Matches lost</em>
<em>22/45 or 44/90</em>
4x + 6 = 9 is the equation
