n = 17x + 5 and

n = 23y + 14

are true statements. Therefore,

17x + 5 = 23y + 14

subtract 5 to both sides and you get 17x = 23y + 19

subtract 2y from both sides and you get 17x - 23y = 9

This is choice B

n/17 = x + 5/17 --> n = 17x + 5 --eqn1

n/23 = y + 14/23 --> n = 23y + 14 --eqn2

Subtract these 2, to give 17x+5 - (23y+14) = 0
17x+5-23y-14 = 0
17x-23y-9 = 0
17x-23y = 9

which is your answer B.
