x = yz + y

 

The answer sheet says the answer is:

 

y = x / z + 1

 

I have followed the rules of doing the same to both sides etc but cannot get to this answer or work out where the 1 has come.

 

Please help.

x = yz + y

 

Make y the subject.....note that the right side can be factored as

 

x  = y (z + 1)       now....divide both sides by (z + 1)   and we have that

 

x / ( z + 1)   =  y

 

 

cool cool cool
