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

so 7/4 is the answer or do i solve that?

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

is that right or wrong?

the numerator is right except it's a negative and the denominator is wrong

how did i get the denominator wrong?

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

yea and i got that big fraction

try plugging in your answer into that equation
 one year ago

ArkGoLuckyBest 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

when you do this, you get 16=7(9+4x) I'm sure you can solve for x now
