um I don't think this is possible because the numerator of the first fraction is not changed so it can't equal the second fraction. ever

not quite. I'll just show you the equation. So you know that the number x, when multiplied by the numerator(4) then added to the denominator(9) equals 7/4 That means 4/9+4x=7/4

KE8717504 Group TitleBest ResponseYou've already chosen the best response.0
so 7/4 is the answer or do i solve that?
 2 years ago

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
no, now you solve for x, which is the number you're looking for

KE8717504 Group TitleBest ResponseYou've already chosen the best response.0
is that right or wrong?
 2 years ago

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
the numerator is right except it's a negative and the denominator is wrong

KE8717504 Group TitleBest ResponseYou've already chosen the best response.0
how did i get the denominator wrong?
 2 years ago

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
did you solve x in\[\frac{ 4 }{ 9+4x }=\frac{ 7 }{ 4 }\]

KE8717504 Group TitleBest ResponseYou've already chosen the best response.0
yea and i got that big fraction

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
try plugging in your answer into that equation
 2 years ago

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
okay I'll show you how to solve for x multiply both sides of the equation by the common denominator. In this case, it is (4)(9+4x) this is to rid of the fractions
 2 years ago

ArkGoLucky Group TitleBest ResponseYou've already chosen the best response.0
when you do this, you get 16=7(9+4x) I'm sure you can solve for x now
