Answer:
d = 24
Step-by-step 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
