9n + 6 = 45 rounded to the nearest hundred

It's a fraction but to the nearest hundred it's, n=4.3

Answer: 4.33

Work Shown:

9n + 6 = 45

9n + 6 - 6 = 45 - 6 ... see note 1 below

9n = 39

9n/9 = 39/9 ... see note 2 below

n = 39/9

n = 4.333333 ... the 3's go on forever

n = 4.33

note 1: Subtract 6 from both sides. This is to undo the + 6

note 2: divide both sides by 9 to undo the multiplication
