Please explain step by step how to solve. Thank you

By doing cross multiply, you'll get
6(p-1) = 8(p+10)
Expand
6p-6 = 8p+80
Arrange
-80-6 = 8p-6p
-86 = 2p
Divide by 2 to find p
-43 = p
Answer:
p =
Step-by-step explanation:
First, we can start by cross multiplying.
p−1p+10=86
(p−1)*(6)=8*(p+10)
6p−6=8p+80
After some simplification, we get:
−2p=86
Then we find out that p = -43
If we put it in, and then simplify that, we will get 8/6
