Answer 2

Ответ:

-3а + 7d - 8a - 6d = - 3a - 8a + 7d - 6d = - 11a + d

Answer 3

To simplify the expression (-3a + 7d) - (8a + 6d), you can use the distributive property to remove the parentheses and then combine like terms. Here's the step-by-step simplification:

1. Distribute the negative sign (-) to both terms inside the second parentheses: (-3a + 7d) - 1*(8a) - 1*(6d)

2. Now, distribute the -1 to both terms inside the second parentheses: -3a + 7d - 8a - 6d

3. Combine like terms. Group the "a" terms and the "d" terms together: (-3a - 8a) + (7d - 6d)

4. Perform the arithmetic operations within each grouping: -11a + 1d

So, the simplified expression is: -11a + d.
