Best ResponseYou've already chosen the best response.1um, its from the nine chapters on chinese mathematics, its a 400 level math history class, but this math should not be hard... I just have no idea how to do it for some reason. I try and expand everything and it gets very very very ugly..and I get lost in it.

Best ResponseYou've already chosen the best response.0When I see i, I think the imaginary number. When I see e I think of another constant. I would have to change the variables to have a chance of working the problem.

Best ResponseYou've already chosen the best response.3\[x=\frac{ cb }{ a }\] now find \[\frac{ cb }{ a } \] from \[ai+b=c+d, ai+b=c+e\]

Best ResponseYou've already chosen the best response.3aid=cb and aje= cb now add above equations a(i+j) (d+e)=2(cb) now divide both sides by a \[(i+j)\frac{ d+e }{ a }=2\frac{ cb }{ a }=2x\] i think now you can do it :)

Best ResponseYou've already chosen the best response.3also if you subtract aid=cb from aje=cb you will have a(ji)=ed therefore\[a=\frac{ ed }{ ji }\] now plug in a and rationalise

Best ResponseYou've already chosen the best response.3well i am sorry i wasnt here , you have to put value of a in to the fraction\[(i+j)\frac{ d+e }{ a }\] the a in the denominator so that you can rearrange everything and have answer in terms of d and e , i and j only
