The average of the five numbers is 8. If you take one of these numbers and change it to 8, the average is 9. What is the original number before the change?
8 5 [OP_MUL] 9 5 [OP_MUL] 8 [OP_SUB] [OP_SUB]
var_a = 8
var_b = 5
var_c = var_a * var_b
var_d = 9
var_e = 5
var_f = var_d * var_e
var_g = 8
var_h = var_f - var_g
var_i = var_c - var_h
print(int(var_i))
