Best ResponseYou've already chosen the best response.3first thing I can see do do straight away is to simplify the first fraction by cancelling out those 3's dw:1440351817587:dw

Best ResponseYou've already chosen the best response.3next step is to take a look at our denominators: x (x+4) and 7x the LCD of these is just x(x+4)(7x) so we want to multiply both sides by x(x+4)(7x)

Best ResponseYou've already chosen the best response.3ok, so I agree that you get x = 0 and x = 3 when you solve; however, one of these is an extraneous solution notice what happens when you plug in x = 0 back into the equation

Best ResponseYou've already chosen the best response.3ok, so we have (7/8)  (1/x) = (3/4) let's start by subtracting (3/4) from each side

Best ResponseYou've already chosen the best response.3well, the left side is (7/8)  (1/x) and the right side is (3/4) so, let's start by subtracting (3/4) from the left side (7/8)  (1/x)  (3/4) = ?
