You can put this solution on YOUR website!
let a be the larger nunmber.
let b be the smaller number.

the average is 84.

you get (a + b) / 2 = 84

multiply both sides of this equation by 2 and you get a + b = 168.

the range is 16.

you get a - b = 16.

solve these 2 equations simultaneously and you should get your answer.
