What is the value of p in the equation 4p + (10+5p) = 7?

-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!
