**Reiny**, Sunday, January 16, 2011 at 3:35pmI am not a fan of fractions in equations, so I usually multiply each term by the LCD, in this case 15

9k - 15(k+1/3) = k+3

9k - 15k - 5 = k + 3

-7k = 8

k = -8/7

remove ( )

3/5k - k - 1/3 = 1/15k + 3/15

get rid of denominators

since 15 is the LCD of 5, 3, 15

multiplying both sides by 15 will do this

15 (3/5k - k - 1/3) = 15(1/15k + 3/15)

9k - 15k - 5 = k + 3

-6k - 5 = k + 3

-7k = 8

k = -8/7
