Step-by-step explanation:

11. 10- (3p-4) = 4(p+1)+9

10 - 3p + 4 = 4p + 4 + 9

14 - 3p = 4p + 13

-3p - 4p = 13 - 14

-7p = -1

p = -1/-7

p = 1/7

12. 4y + y/5 =21

(20y+y)/5 = 21

(21y)/5 = 21

21y = 21*5

y = 105/21

y = 5

13. -3/8 * [4/7 + (-11/7)]

-3/8 * 4/7 + -3/8 * -11/7

= -12/56 + 33/56

= -12+33/56

= 21/56
