Question 938339: If you reverse the two digits of the age Roger reached yesterday, multiply by three and add six, you'll have Roger's age . How old is Roger? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! 3(10u+t) + 6 = 10t + u
30u + 3t + 6 = 10t + u
29u - 7t + 6 = 0
u = 1 , t = 5
Roger is 51
.......
and..checking
3(15) + 6 = 51
