3 times the difference of 7 and d

3x - 7 + d

3(7-d)

To find the answer, you need to subtract d from 7 and then multiply the result by 3. Here are the step-by-step instructions:

1. Start with the number 7.
2. Subtract d from this number: 7 - d.
3. Multiply the result by 3: 3 * (7 - d).

So, the final expression is 3 * (7 - d).

To find 3 times the difference of 7 and d, you need to follow these steps:

1. Start by subtracting d from 7.
The difference of 7 and d can be calculated as 7 - d.

2. Multiply the difference by 3.
Take the result from step 1 and multiply it by 3.

So, in mathematical terms, 3 times the difference of 7 and d can be represented as: 3 * (7 - d)
