Answer:

d = 24

Explanation:

d/4-9=-3

We simplify the equation to the form, which is simple to understand

d/4-9=-3

Simplifying:

+ 0.25d-9=-3

We move all terms containing d to the left and all other terms to the right.

+ 0.25d=-3+9

We simplify left and right side of the equation.

+ 0.25d=+6

We divide both sides of the equation by 0.25 to get d.

d=24
