Answer 1

Multiplied both sides by 3 to remove 3 from denominator

 

3*(X+9)/3=8*3

 

x+9=24

 

Subtract 9 from both sides

x+9-9=24-9

 

x=15

Answer 2

(x + 9)/3 = 8

x + 9 = 24       multiply both sides by 3

x = 15             subtract 9 from both sides

Answer 3

You can go a couple ways with this one. You can divide both terms on the left by 3 and work with the fractions, or you can multiply both sides by 3 to clear out the fraction and you are then working with whole numbers. My opinion, clearing out the fraction is easier. So I will proceed this way:

 

(x+9) / 3 * 3 = 8 * 3

x+9 = 24

x + 9 - 9 = 24 - 9

x = 15
