Antwoord:

Het antwoord is #option (3) #

Uitleg:

# X + b / x = a #

#=>#, # X ^ 2 + b = ax #

#=>#, # X ^ 2 = ax-b #

#=>#, # X ^ 3 = ax ^ 2-bx #

#=>#, # Ax ^ 2-bx = a + 1 #

#=>#, # Ax ^ 2 = bx + a + 1 #

#=>#, #a (ax-b) = a + bx + 1 #

#=>#, # A ^ 2x-bx = ab + a + 1 #

#=>#, # (A ^ 2-b) x = ab + a + 1 #

#=>#, # X = (ab + a + 1) / (a ^ 2-b) #, # (A ^ 2-b)! = 0 #

Het antwoord is #option (3) #
