Answer 1

Hi,

 

 

     2/a - 1 = 4 / y ; where a and y cannot equal zero. What is y in terms of a?

 

First we mulipy the entire equation by a common denominator.

This is case the common denominator is ay

 

ay[2/a - 1 = 4/y]

2y-ay=4a        Factor out the y

y[2-a]=4a       Divide by [2-a]

 

y= 4a

    ----

     2-a

 

ANSWER: 

y=  4a
     ----
      2-a
