if the average of 37 , 69 , 47 and x is 46.5 , what is x ?
"x = 33 because : ( 37 + 69 + 47 + x ) / 4 = 46.5 ( 37 + 69 + 47 + x ) / 4 * 4 = 46.5 * 4 ( 37 + 69 + 47 + x ) = 186 ( 37 + 69 + 47 + x ) - 153 = 186 - 153 x = 33 therefore , the answer is e , 33 ."
add(multiply(37, const_2), multiply(subtract(69, multiply(37, const_2)), 37))
