The numerator and denominator of a fraction are in the ratio of 3 to 5. If the numerator and denominator are both increased by 2, the fraction is now equal to 2/3.

If n = the numerator and d = the denominator, which of the following systems of equations could be used to solve the problem?

A) 5n = 3d and 3n + 6 = 2d + 4

B) 5n = 3d and 4n + 4 = 3d + 6

C) 3n = 5d and 3n + 6 = 2d + 4
