Answer 1

P=3r + 2s       you need to get all the numbers and variables on the other side                               of the equation so that s is alone. 
P -3r = 2s          Subtract the 3r from both sides. 
P- 3r /2 =s         now divide the whole amount P-3r by 2 and you've got your                                answer!
