Best ResponseYou've already chosen the best response.0not 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

Best ResponseYou've already chosen the best response.0so 7/4 is the answer or do i solve that?

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

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

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

Best ResponseYou've already chosen the best response.0okay 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

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