Nine less than a number times four equals fifteen
basically, x*4-9=15 would be your equation, or something similar
Well, we know x can't equal 1,2,3,OR 4. Five is also out, because 5*4=20-9=11, so cross that out.
But if you try doing 6*4-6=15, it fits.
6*4=24, 24-9=15
Thus, x=6, so your answer to Nice less than four times a number equals fifteen is 6.

Some states let you retake it and give you a second chance m, if your country doesn't do that then you have higher chance to take more, every year you get to take one and it determines if you get credit or honors, you can also do community service to get you more points, that helps a lot too once you get to a higher grade you get more options and tests you can take for credits and honors, I wouldn't be that worried.:)
