If we add a certain number to 18, and then divide it by 3, and then add 10, and then divide by 5, we get 4 as a result. Find out the number in question.
4 5 [OP_MUL] 10 [OP_SUB] 3 [OP_MUL] 18 [OP_SUB]
var_a = 4
var_b = 5
var_c = var_a * var_b
var_d = 10
var_e = var_c - var_d
var_f = 3
var_g = var_e * var_f
var_h = 18
var_i = var_g - var_h
print(int(var_i))
