Problem: if the average ( arithmetic mean ) of x , x + 2 , and x + 4 is 73 , what is the value of x ?
Rationale: "am of x , x + 2 , and x + 4 = x + ( x + 2 ) + ( x + 4 ) / 3 = 3 x + 6 / 3 = x + 2 given that x + 2 = 73 x = 71 answer : a"
annotated_formula: subtract(multiply(4, const_2), multiply(2, const_2))
