Answer:

k = 6

Explanation:


(3k)/(2) -
(k+3)/(3) = 8 -
(k+2)/(4)

multiply through by 12 ( the LCM of 2, 3 and 4 ) to clear the fractions

18k - 4(k + 3) = 96 - 3(k + 2) ← distribute parenthesis on both sides

18k - 4k - 12 = 96 - 3k - 6

14k - 12 = - 3k + 90 ( add 3k to both sides )

17k - 12 = 90 ( add 12 to both sides )

17k = 102 ( divide both sides by 17 )

k = 6
