The numerator of a fraction is 1 more than twice its denominator. if 4 is added to both the numerator and the denominator, the fraction reduces to 5/3. find the denominator

(2d + 1) / d

(2d + 1 + 4) / (d + 4) = 5/3

(2d + 5) / (d + 4) = 5/3

3 (2d + 5) = 5 (d + 4)

6d + 15 = 5d + 20

6d - 5d = 20 - 15

d = 5

(11 + 4) / (5 + 4) = 5/3

15/9 = 5/3

5/3 = 5/3 (correct)

ur numerator is 11, ur denominator is 5 ... adding 4 to each gives u 15/9, which reduces to 5/3

5.

the equation looks like:

((2x+1) + 4) / ((x) + 4) = 5/3

then you do cross multiplication and get:

6x+3+12=5x+20

subtract 5x on each side. subrtract the 3 and 12 from the 20.

and you get your answer 5=x
