d =

Explanation:

Step1: Simplify the right - hand side

The equation $56 = d-(- 54)$ simplifies to $56 = d + 54$ since subtracting a negative number is the same as adding a positive number.

Step2: Isolate the variable $d$

Subtract 54 from both sides of the equation: $56-54=d+54 - 54$.
$d=56 - 54$
$d = 2$

Answer:

$2$
