Final answer:
To solve the equation, we translate the difference of -2d and -3d into the equation -2d - (-3d) and the difference of 16 and 13 into the equation 16 - 13. Solving the equation, we find that d = 3.
Step-by-step explanation:
To solve the equation, we translate the phrase 'the difference of -2d and -3d' into the equation '-2d - (-3d)'. We also translate 'the difference of 16 and 13' into the equation '16 - 13'. Now, we can solve the equation:
-2d - (-3d) = 16 - 13
-2d + 3d = 3
d = 3
Therefore, the solution to the equation is d = 3.
