Let's look for key words. We have more, times, is, and times. Order is important, so let's look for "a number". We have 3 times a number. So 3x. We have 9 more than that, so 3x+9. we have is, so that equals something. What does it equal? 10x. So 3x+9=10x is your equation. you can solve this and be sure it works. Here, 7x=9, so x=9/7. Three times 9/7 is 27/7, and 9 more makes that (63+27)/7, or 90/7. 10 times 9/7 is 90/7, so they are the same, and the equation makes sense. But you were asked only for the equation, not the solution, so if fractions are an issue for you, feel free to partially ignore that:)
