Answer:
1) 14 2) 6 3) 53 4)-2
Step-by-step explanation:
1) 15 - n/7 = 13
7*15 - 7*n/7 = 7*13
105 - n = 91
-n = 91 - 105
-n = -14
n = 14
2) 44 = - 4 + 8p
-8p = - 4 - 44
-8p = -48
-p = - 48/8
-p = 6
3) 21 - h= -32
-h = -32 -21
-h = -53
h = 53
4) -19 = 11b + 3
-11b = 19 + 3
-11b = 22
-b = 22/11
-b = 2
b = -2
We can remove parenthesis if we change the sign of all terms in the second parenthesis (because we're subtracting it).
So, we have

And now we simply have to aggregate like terms:

0? I honestly had to think about this cause I’m so tired but tryna help folks lol
