Best ResponseYou've already chosen the best response.0To solve rational equations, all you have to do is get rid of the denominators (by multiplying both sides by them), solve as you would a normal equation, and then make sure your solutions wouldn't make the original denominators equal zero. In this case, then, your first step should be to multiply both sides by \(b\), as the two fractions (\(\frac{1}{2b}\) and \(\frac{b+1}{b}\)) have the denominator \(b\).

Best ResponseYou've already chosen the best response.0ok soo what we can get here is the following: 1 = (1/2b)  (b+1)/b 1 = (1/2b)  (2/2)(b+1)/b so we get 1 = (1/2b)  (2b +2)/2b 1 = (1  2b 2) / 2b so we get 1=2b1/2b 2b = 2b 1 2b+2b = 1 4b = 1 sp b = 1/4

Best ResponseYou've already chosen the best response.0well you are just trying to simplify by using common denominators because they are fractions. right? its like adding (1/2) + (1/4)
