Best ResponseYou've already chosen the best response.0\[\frac{x3}{x5}=\frac{x+2}{x7}+1\] \[\frac{x3}{x5}\frac{x+2}{x7}1=0\] \[=\frac{(x7)(x3)}{(x7)(x5)}\frac{(x5)(x+2)}{(x5)(x7)}\frac{(x5)(x7)}{(x5)(x7)}\] \[=\frac{(x7)(x3)(x5)(x+2)(x5)(x7)}{(x7)(x5)}\]

Best ResponseYou've already chosen the best response.1(x3)(x7) = (x5)(x+2) + (x5) = x^(2)  10x + 21 = x^(2)  3x  10 = Im sure you can solve it from here but if you dont know how I got (x3)(x7) = (x5)(x+2) + (x5) from your original problem then say so

Best ResponseYou've already chosen the best response.1x^(2)  10x + 21 = x^(2)  3x  10 = 10x + 3x = 10  21 = 7x = 31 x = 31/7 = x = 31/7

Best ResponseYou've already chosen the best response.1that is your answer the rest of the people who attempted this problem need a refresher on algebra and solving equations or they just did things the long way

Best ResponseYou've already chosen the best response.1well first you always want to bring all x terms into the numerator so to do this I multiplied both sides of the equation by (x5) and (x7) so (x3)(x5)(x7)/(x5) = (1 + (x+2)/(x7)) * (x5)(x7) = (x3)(x7)(1) = (x5)(x7) + (x5)(x7)(x+2)/(x7) = (x3)(x7) = (x5)(x7) + (x5)(x+2)(1) = (x5)(x7) + (x5)(x7)(x+2) = (x5)(x7) + (x5)(x+2) = Now expand everything Looks like I made a mistake :S

Best ResponseYou've already chosen the best response.1ugh my brain it is dead. (x3)(x5)(x7)/(x5) = (1 + (x+2)/(x7)) * (x5)(x7) = (x3)(x7)(1) = (x5)(x7) + (x5)(x7)(x+2)/(x7) = (x3)(x7) = (x5)(x7) + (x5)(x+2)(1) = (x3)(x7) = (x5)(x7) + (x5)(x+2) Now expand and simplify to get the answer
