g/e^2 - r = m- y     add r to both sides

 

g      =   m - y  + r

__       _________       we can "flip" both fractions and still keep equality...so...

e^2          1

 

 

 

e^2    =      1

____       ________          multiply both sides by g

g             m - y + r

 

 

e^2     =    g   / [ m - y + r ]        take both roots

 

 

e   =  ±√  [ g   / ( m - y + r )  ] 

 

 

 

cool cool cool
