You can put this solution on YOUR website!
(1) +s+=+3p+-+2+
Subtract +3p+ from both sides
(1) +s+-+3p+=+-2+
and
(2) s+=+2p+%2B+1+
Subtract +2p+ from both sides
(2) +s+-+2p+=+1+
Subtract (2) from (1)
(1) +s+-+3p+=+-2+
(2) +-s+%2B+2p+=+-1+
+-p+=+-3+
+p+=+3+
and, since
(2) s+=+2p+%2B+1+
(2) +s+=+2%2A3+%2B+1+
(2) +s+=+6+%2B+1+
(2) +s+=+7+
