The error occurred in step 2. You have to use the distributive property for the parenthesis. It is supposed to be 5p+15.
The correct solution is p>-13.

1st step you subtract 7 from both sides and the 7 get cancelled so you will get

2nd step you divide by 10 from both sides so you will get

3rd step is that you final answer is
Answer:
[1,2], [2,1], [3,0]
Step-by-step explanation:
To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.
From our graph(attached) we multiply any three solutions by a -1:

Hence, the 3 solutions are [1,2],[2,1],[3,0]
