Question

Three consecutive integers have a sum of 84, how do you find the integers?

Answer 1

To solve this, you represent the the question as:
`x+ (x+1)+ (x+2)=84`

Explanation:

Three consecutive integers can be represented as `x, x+1, x+2`.
If those three integers sum to 84, then
`x+ (x+1)+ (x+2)=84`
and then we simplify
`x+ x+1+ x+2=84`
`3x+ 3=84`
`3x=84-3`
`x=81/3 = 27`
so

`x=27`
`x+1=28`
`x+2=29`
