Question

What 2 consecutive integers have a sum of 39?

Answer 1

`19 & 20` are the reqd. integers.

Explanation:

If one integer is `x`, the other has to be `x+1`, being consecutive to `x.`

By what is given, `x+(x+1)=39.`

`:. 2x+1=39.`

`:. 2x=39-1=38.`

`:. x=19,` so, `x+1=20.`

Thus, `19 & 20` are the reqd. integers.
