Question

what is the LCD (lowest common denominator) that would be used to eliminate the fractions in the following equation? 3/x+4+5/4x=3/4x

Answer 1

To find the LCD of the equation:

`(3)/(x+4)+(5)/(4x)=(3)/(4x)`

We multiply the differents denominator, then in this case we have that the LCD is:

`4x(x+4)`
