Simplify 9+3(4a-7)-5a+6.

Answer 1

9 + 3(4a - 7) - 5a + 6 can be simplified as follows:

First, distribute the 3 to the terms inside the parentheses:

9 + 12a - 21 - 5a + 6

Next, combine like terms:

(12a - 5a) + (9 - 21 + 6)

Simplify within the parentheses:

7a + (-6)

Combine like terms:

7a - 6

So, 9 + 3(4a-7) - 5a + 6 simplifies to 7a - 6.
