= 6a - 3b - 6a - 8b = (6a - 6a) - (3b + 8b) = - 11b.

Answer 2

To simplify the expression 3(2a - b) - 2(3a + 4b), you can distribute the coefficients (3 and -2) to the terms inside the parentheses and then combine like terms:

3(2a - b) - 2(3a + 4b)

= (3 * 2a - 3 * b) - (2 * 3a + 2 * 4b)

= (6a - 3b) - (6a - 8b)

Now, distribute the negative sign inside the second parentheses:

= 6a - 3b - 6a + 8b

Now, combine like terms:

= (6a - 6a) + (-3b + 8b)

The 6a and -6a terms cancel each other out, and you're left with:

= 0a + 5b

Since anything multiplied by 0 is 0, the term with 'a' disappears, and you're left with:

= 5b

So, the simplified expression is 5b.

Answer 3

To simplify the expression 3(2a - b) - 2(3a + 4b), you can distribute the constants outside the parentheses into the expressions inside the parentheses and then combine like terms. Here's how you can do it step by step:

1. Distribute the 3 into the first set of parentheses and the -2 into the second set of parentheses:

   3 * 2a - 3 * b - 2 * 3a - 2 * 4b

2. Now, multiply the constants with the variables inside the parentheses:

   6a - 3b - 6a - 8b

3. Next, combine like terms. In this case, the 6a and -6a will cancel each other out, and the -3b and -8b can be combined:

   (6a - 6a) - (3b + 8b)

4. Finally, simplify further:

   0 - 11b

So, the simplified expression is -11b.
