Answer:

d = 24

Explanation:


\rm \implies - (2)/(3) d - (1)/(4) d = - 22 \\ \\ \rm \implies - (2)/(3) d * (4)/(4) - (1)/(4) d * (3)/(3) = - 22 \\ \\ \rm \implies - (8)/(12) d - (3)/(12) d = - 22 \\ \\ \rm \implies ( - 8d - 3d)/(12) = - 22 \\ \\ \rm \implies \cancel{- } (11)/(12) d = \cancel{-} 22 \\ \\ \rm \implies d = 22 * (12)/(11) \\ \\ \rm \implies d= 2 * 12 \\ \\ \rm \implies d= 24
