Answer 1

Answer:

83

Step-by-step explanation:

let x be the unit digit and y the tens digit  

given:  

The sum of the digits is 11: y%2Bx=11.......1  

The tens digit in a two digit number is 2 more than twice the units digit.  

y=2x%2B2........2

y%2Bx=11........substitute y from 2  

2x%2B2%2Bx=11  

3x=11-2  

3x=9  

highlight%28x=3%29.........the ones digit  

y=2x%2B2........2  

y=2%2A3%2B2  

highlight%28y=8%29..........the tens digit
