Best ResponseYou've already chosen the best response.2i am going with cross, x(x1) = 2(x+2)

Best ResponseYou've already chosen the best response.2@Adi3 good stuff tip: in an exam, i would actually take those numbers and put them back into the original equation just to be triply sure :p

Best ResponseYou've already chosen the best response.2ie plug 4 and 1 into \(\frac{ x1 }{ x+2} = \frac{ 2 }{ x }\) to check them....

Best ResponseYou've already chosen the best response.2put them in separately so for x = 4 \(\frac{ x1 }{ x+2} = \frac{ 2 }{ x } \implies \frac{ 41 }{ 4+2} = \frac{ 2 }{ 4 }\) that is \(\frac{3}{6} = \frac{2}{4} \checkmark\)
