Math Review
Question: 9
Page: 244
Difficulty: medium

Let x = the UNITS digit
So, x+5 = the TENS digit [since we're told the tens digit is 5 more than the units digit]

The sum of the digits is 11.
We can write: x + (x + 5) = 11
Simplify: 2x + 5 = 11
So: 2x = 6
Solve: x = 3
So, the UNITS digit is 3, which means the TENS digit is 8

Find the integer.
The number is 83

Cheers,
Brent
