Best ResponseYou've already chosen the best response.2\[\frac{ 5 }{ x2 }  \frac{ 20 }{ (x2)(x+2) } = 1\] now you may use rule \[\frac{ a }{ b }  \frac{ c }{ d } = \frac{ adbc }{ bd }\]

Best ResponseYou've already chosen the best response.0yeah so there can be infinite solution but u cant try it out maybe is there a formula to find it out ?

Best ResponseYou've already chosen the best response.2It is not infinite solutions :P

Best ResponseYou've already chosen the best response.2An equation would have infinite many solutions if the equation has equal values for all variables. So if we had something such as y = x, unless stated otherwise.

Best ResponseYou've already chosen the best response.0Well from what I'm doing, it's turn out to be answer B...:(

Best ResponseYou've already chosen the best response.2Well lets see...if we simplify it a bit more we should get \[5(x+2)20=(x2)(x+2) \implies 5x10=x^24 \implies x^25x+6 = 0\] do you know how to factor?

Best ResponseYou've already chosen the best response.2I don't think you do, I think you're just guessing, if you factor \[x^25x+6=0\] you will get your answer.

Best ResponseYou've already chosen the best response.1there can be only one unknown? really? Last time I checked there are math problems that make you solve for 3 unknowns. x=? y = ? z = ? Factoring out that equation in this case, gives out more than one x = ?

Best ResponseYou've already chosen the best response.2I think they just assumed it before doing the math :P
