-3x + 18 = 7x - 12

we want to get x on only one side so you would add 3x to 7x

18 = 10x - 12

next, we want the 18 and 12 on the same side so you add 12 to 18

30 = 10x

finally we want the x by itself so you will divide 10x and 30 (since you need to do it for both sides) by 10

final answer:

10 = x

or

x = 10

Answer:

6.) So 8 of 24 hours is 1/3. So the percent of his time used was <u><em>33.33333 . . %</em></u> (etc)

7.) The easiest way to figure out a percentage is dividing it. So if it was 30 hit out of 75 people, then divide 30 by 75. So <u><em>40%</em></u> of them got hit.

Hope that helps
