    Step 1. Combine all like terms where they are. In your case, combine all like terms on the right side \(9p-15=p+5p-2p\) \(9p-15=4p\) There are no like terms on the left side, so step 1 is done. Ok so far?

    Step 2. Now we want all terms with p on the left side, so we subtract 4p from both sides. \(~~~9p-15=~~~4p\) \(-4p ~~~~~~~~~~~~~-4p\) We get: \(5p - 15 = 0\)

    Step 3. Now we want the number (with no variable) on the right side, so we add 15 to both sides. \(~~~5p - 15 ~~~= ~~~~~~0\) \(~~~~~~~~+15~~~~~~~+15\) We get: \(5p = 15\) Ok so far?

    Correct. Step 4. We want p alone, so we divide both sides by 5 \(\dfrac{5p}{5} = \dfrac{15}{5} \) \(p = 3\)
