1. 6q + 3p² - 5q + 4p² + q
= 6q - 5q + q + 3p² + 4p²
= 2q + 7p²

2. 8 - (-12) = 8 + 12 = 20

3. -11 + x = -21
x = -21 + 11
x = -10

4. -k x 12 = -72
-12k = -72
k = -72/-12
k = 6

5. 91 : n = 13
13n = 91
n = 91/13
n = 7

6. (8 x 17) - (96 x 9)
= 136 - 864
= 1000

8. 5a - 7b - 5c
= (5 x 3) - (7 x -4) - (5 x 10)
= 15 - 28 - 50
= -63
