Best ResponseYou've already chosen the best response.0no value of x satisfies that. because if you rearrange it you would get x=10x/5 as you know no number can be defined like that unless it is 0

Best ResponseYou've already chosen the best response.0the x terms on both sides gets cancelled leaving away no solution

Best ResponseYou've already chosen the best response.0That is the solution but I am curious why can't you make it x=9/10x? and then go from there 10x^2=9 x^2=9/10 x=3/sqrt10

Best ResponseYou've already chosen the best response.05/x=9/2x multiply both sides by x 5=9/2???? no solution

Best ResponseYou've already chosen the best response.0Why can't you multiply both sides by 1/5 instead of x?

Best ResponseYou've already chosen the best response.0an unreal solution would be x=infinity infact 2 unreal solutions > inf and inf

Best ResponseYou've already chosen the best response.0There would be infinite solutions ? @shubhamsrg or no solutions ?

Best ResponseYou've already chosen the best response.0I guess they are infinite solutions.

Best ResponseYou've already chosen the best response.0I understand the answer is no solution what I am asking is why can't you divide by 5 to get x by itself.

Best ResponseYou've already chosen the best response.02 solns, 2 unreal solutions, or should i say 2 theoretical solutions.

Best ResponseYou've already chosen the best response.0I guess we should call it infinite solutions.

Best ResponseYou've already chosen the best response.0hmm ? I'd still say 2 solutions which are inf and inf , but both are theoretical .

Best ResponseYou've already chosen the best response.0@saifoo.khan Explain. I remember hero telling me that there would be infinite solutions. I also believed there would be no solution.

Best ResponseYou've already chosen the best response.0Will one of you brilliant people just explain what algebraic rule I am missing/perverting that is making me not see the no solution. Why can't you multiply by 1/5?

Best ResponseYou've already chosen the best response.0@sleipnir234 Ok Lets follow you, \[\huge\frac{ 5 }{ x }=\frac{ 9 }{ 2x }\] Now multiply and divide by 1/5. Let us see what you get.

Best ResponseYou've already chosen the best response.0Now multiply both sides by 1/5 *

Best ResponseYou've already chosen the best response.0\[\frac{ 5 }{ x } \times \frac{ 1 }{ 5 }=\frac{ 9 }{ 2x } \times \frac{ 1 }{ 5 }\]

Best ResponseYou've already chosen the best response.2if you multiply both sides by 1/5, you get 1/x =9/(10x) and not x=9/10x

Best ResponseYou've already chosen the best response.2if there is an identity after cancelling 'x', then there are infinite solutions @hba, here we don't get an identity, ,we get 1=9/10 which is NEVER tru , so, no solution. if we got something like 1=9/9, then we would have infinite solutions

Best ResponseYou've already chosen the best response.0There are, 2 solutions! 2 theoretical solutions, one should not ignore that.
