P+1/p=3

p+1=3p

1=3p-p

1=2p

1/2=p

0.5=p

now

p-1/p

=

0.5-1/0.5

-0.5/0.5

=-1

answer is -1

p+1=3p

1=3p-p

1=2p

1/2=p

0.5=p

now

p-1/p

=

0.5-1/0.5

-0.5/0.5

=-1

answer is -1

Sub -2 from both sides

p+1/p - 2 = 3 - 2

1-p/p = 1

multiplying by -1

p-1/p = -1

p+1/p - 2 = 3 - 2

1-p/p = 1

multiplying by -1

p-1/p = -1
