Final answer:
To solve the equation M/X - r = p using reverse distribution, isolate the variable X by adding r to both sides and then multiplying both sides by the reciprocal of M. The correct answer is b) X = (p + r)/M.
Step-by-step explanation:
To solve the equation M/X - r = p using reverse distribution, we need to isolate the variable X.
First, add r to both sides of the equation to get M/X = p + r.
Next, multiply both sides of the equation by the reciprocal of M to get X = (p + r)/M.
Therefore, the correct answer is b) X = (p + r)/M.
