Final answer:
To solve the equation 3(4d) – 14 = 15 – 5d – 4d, we need to simplify the equation and isolate d. The value of d is 29/21.
Step-by-step explanation:
To find the value of d in equation 3(4d) – 14 = 15 – 5d – 4d, we need to simplify the equation and isolate d on one side of the equation. Let's start:
- Expand the brackets: 12d - 14 = 15 - 9d
- Combine like terms: 12d + 9d = 15 + 14
- Combine the d terms: 21d = 29
- Isolate d by dividing both sides of the equation by 21: d = 29/21
Therefore, the value of d in the equation is 29/21.
