the sum of the digits of a two digit number is 6, If the digits are reversed, the new number is tree times the original tens number. find the original number.

well just playing with the numbers I got 51 as the original number since 15 is 3 times 5

but doing the problem with equations ???

I tried

$t + u = 6$

$3u = 3t$

but this not got it.

thanks ahead
