In a two digit number, the tens digit is 3 smaller than the units digit. if you add this number to the number obtained by swopping the two digits, the sum of these numbers equals 77. determine the original two digit number
***
let u=units digit
let t=tens digit
t=u-3
..
10t+u+10u+t=77
10(u-3)+u+10u+u-3=77
10u-30+u+10u+u-3=77
22u=110
u=5
t=5-3=2
original two digit number=10t+u=20+5=25
