3.- 17a - 20 + 3b + 13 + 24a - 11 - 18b - 6 + 9b = 7a - 6b - 24.......

Combine like terms: 12n + -12n = 0
6 + 0
6

3.Simplifying
-17a + -20 + 3b + 13 + 24a + -11 + -18b + -6 + 9b

Reorder the terms:
-20 + 13 + -11 + -6 + -17a + 24a + 3b + -18b + 9b

Combine like terms: -20 + 13 = -7
-7 + -11 + -6 + -17a + 24a + 3b + -18b + 9b

Combine like terms: -7 + -11 = -18
-18 + -6 + -17a + 24a + 3b + -18b + 9b

Combine like terms: -18 + -6 = -24
-24 + -17a + 24a + 3b + -18b + 9b

Combine like terms: -17a + 24a = 7a
-24 + 7a + 3b + -18b + 9b

Combine like terms: 3b + -18b = -15b
-24 + 7a + -15b + 9b

Combine like terms: -15b + 9b = -6b
-24 + 7a + -6b

1. w + 4 - (- w) - 8 - (- 10) =
w + 4 + w - 8 + 10 =
2w + 6.

2. 12 + 4n - (- 6k) - 6 + 8n + (- 6k) - 12n =
12 + 4n + 6k - 6 + 8n - 6k - 12n =
6.

3. - 17a - 20 + 3b + 13 + 24a - 11 - 18b - 6 + 9b =
7a - 6b - 24.
