Best ResponseYou've already chosen the best response.0Also, I know that \[b \neq 0 \] and \[b \neq x\]

Best ResponseYou've already chosen the best response.1First multiply both sides by (b  x) to eliminate the fraction of the left hand side. Then multiply both sides of the result by 3b to eliminate the fraction on the right hand side. Can you do that?

Best ResponseYou've already chosen the best response.0Well, I get this. If you have time, can you look? (a+x)/(bx)=(4a/3b)*(bx) a+x=4a/3b(bx)*3b 3ba+3bx=4a/bx

Best ResponseYou've already chosen the best response.1Multiplying both sides by (b  x) gives: \[\frac{a+x}{bx}\times (bx)=\frac{4a(bx)}{3b}\] \[a+x=\frac{4a(bx)}{3b}\] Now multiplying both sides by 3b gives: \[3b(a+x)=4a(bx)\] Do you follow so far?

Best ResponseYou've already chosen the best response.1Next multiply out to remove the brackets, then rearrange to get the two terms in x on the left hand side.

Best ResponseYou've already chosen the best response.1Finally you factorise out x and perform a division to get: \[x=\frac{?}{?}\]

Best ResponseYou've already chosen the best response.0Oh,thank you very much. 3ba+3bx=4ab4ax 3bx=4ab3ab4ax 3bx+4ax=ab x(3b+4a)=ab x=ab/3b+4a correct?
