There are 5 times as many blue marbles as red marbles, and yellow marbles are three times more than red marbles. If the total number of blue marbles and yellow marbles is 160, how many red marbles are there?
160 5 3 [OP_ADD] [OP_DIV]
var_a = 160
var_b = 5
var_c = 3
var_d = var_b + var_c
var_e = var_a / var_d
print(int(var_e))
