Answer:
p=(q-2r)/2
Step-by-step explanation:
First, you must isolate the variable p, as you are solving for it. To do this, you substract 2r from both sides. Then, you are left with 2p=q-2r. To fully isolate p, you must divide both sides by 2. Lastly, you are left with p=(q-2r)/2.
Hope this helps :)
