Answer:
-1/3
Step-by-step explanation:
First off, you need to add the common variables like 4p and 5p which is 9p.
Now we have,
9p + 10 = 7
-10 -10
9p = -3
Here were going to have to isolate the variable, the variable really hates that 9 so let's divide them.
9p/9 = p so now "p" is single. That was our goal but what's it's value?
We're going to need to divide -3/9 to get a really long decimal so we can just simplify it to -1/3. And that's why -1/3 is the answer.
Hope that helps and have a great day!
