See a solution process below:

Add $color(red)(2 1/12)$ to each side of the equation to solve for $d$ while keeping the equation balanced:

$d - 2 1/12 + color(red)(2 1/12) = 3 1/12 + color(red)(2 1/12)$

$d - 0 = 3 + 1/12 + color(red)(2) + color(red)(1/12)$

$d = 3 + color(red)(2) + 1/12 + color(red)(1/12)$

$d = 5 + 2/12$

$d = 5 + 1/6$

$d = 5 1/6$
