Final answer:
To solve the equation (3d)/14 = -3, isolate the variable 'd' by multiplying both sides by 14 and then dividing both sides by 3. The solution is d = -14.
Step-by-step explanation:
To solve the equation (3d)/14 = -3, we need to isolate the variable 'd'. We can start by multiplying both sides of the equation by 14 to get rid of the fraction: (3d)/14 * 14 = -3 * 14. This simplifies to 3d = -42. Next, divide both sides of the equation by 3 to solve for 'd': 3d/3 = -42/3. This simplifies to d = -14. Therefore, the solution to the equation is d = -14.
