**drwls**, Wednesday, March 4, 2009 at 2:31am1)Let the two digits be A and B, with A being the first digit.

A + B = 14

10A + B - (10B + A) = 18

9A -9B = 18

A - B = 2

2A = 16

A = 8

B = 6

The first two-digit number is 86.

2) Use a similar procedure for #2

A + B = 11

10A + B + 27 = 10 B + A

9A -9B +27 = 0

You finish it
