Question 1054976: In a number of two digits, the units digit is 3 less than twice the tens digit and the number is 6 less than 9 times the units digit. Find the number. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let m and n be the digits in your two digit number. Then:
2m-3=n
10m+n+6=9n
So, substituting for n, we get:
10m+2m-3+6=9(2m-3)
12m+3=18m-27
6m=30
m=5
n=7
The number is 57. ☺☺☺☺
