@shivraj , why don't you post the result you get after cross multiplication.

Here we can do it by another simple method..

Hero Group TitleBest ResponseYou've already chosen the best response.1
You mean a method other than cross multiplication?

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Let @shivraj solve first and at last I will tell the method..

Okay, so @waterineyes will probably simplify the right fraction before cross multiplying. But that's nothing new.

I will not use cross multiplication anywhere in my solution @Hero

So how will your method be "simpler"?

Can i show you??

I can see that the fraction will be reduced to 4x = 4/3

But now you still have to cross multiply. Doing anything else will just produce more steps.

I won't i said @Hero

Hero Group TitleBest ResponseYou've already chosen the best response.1
err, I mean the fraction will be reduced to 4/x = 4/3 typo above

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Yes: \[\frac{4}{x} = \frac{4}{3} \implies \frac{4}{x} = \frac{4}{3} \implies x = 3\]

Oh, I see what you did. Yeah, in that case, I guess you don't need to cross multiply. Nice trick.

That is what I am trying to say..

Hero Group TitleBest ResponseYou've already chosen the best response.1
That's why the real first step is to actually simplify whenever possible

Usually when I see a proportion, my first impulse is to cross multiply

@waterineyes : Unknowingly you are cross multiplying the terms with 1. :) Still it's a good and simpler method. Well done.

See the way to look this problem is : If; \[\frac{x}{y} = \frac{x}{z}\] then y must be equal to z that is why they become equal.. That is the trick here.. @Champs

You are of course saying it mathematically but I am saying it logically...

What do you call that? The Denominator Equivalency Property?
 2 years ago

waterineyes Group TitleBest ResponseYou've already chosen the best response.1
Ha ha ha.. You can call that what you like..

Hero Group TitleBest ResponseYou've already chosen the best response.1
Or perhaps the Denominator Equality Property

I like it. :)

We see in this Problem that when a single fraction is equal to a single fraction, then the equation can be cleared by "crossmultiplying." If a c  =  b d , then ad = bc.  PROBLEM BELOW  x − 3 x − 5  =  <=== SOLVE 3 2 Here is the cleared equation and its solution: 2(x − 3) = 3(x − 5) 2x − 6 = 3x − 15 2x − 3x = − 15 + 6 −x = −9 x = 9
