First, you have to find what 80% of 15 is. In order to do that you have to change 80% percent to decimal, which would be .80. Then, multiply .80 and 15 to get 12. Subtract 12 from 15 and your answer is 3.

4p-7=13
After the first step which is combining like terms, so add the 3p and the single p together.
Next, the negative 7 turns to a positive when we exterminate it from one half of the equation and add it towards the second part.
4p-7=13
+7. +7
4p=20
Divide both sides by 4 to get the p alone.
4p=20
/4. /4
P=5
That is the answer to the entire equation, again though the first step answer is at the very top, i just felt like solving it for you as well.
