Answer: p=8
Step-by-step explanation:
4p-11=21
We move all terms to the left:
4p-11 - (21) = 0
We add all the numbers together, and all the variables
4p-32=0
We move all terms containing p to the left, all other terms to the right
4p=32
p=32/4
p=8

p=-8
Step-by-step explanation:
21=-4p-11
1) Add 11 to both sides:
32=-4p
2) Divide both sides by - 4 to isolate p:
p=-8
