the average ( arithmetic mean ) of 27 , 32 , and 64 is 6 less than the average of 29 , 42 , and x . what is x ?
"the average of 27 , 32 , and 64 is 41 . the average of 29 , 42 and x is 47 . then 29 + 42 + x = 141 . x = 70 . the answer is e ."
subtract(add(add(27, 32), 64), add(add(multiply(6, const_3), 29), 42))
