Ung number 2 . Pati na rin solution

 

[conviction]

the tens digit of a number is 3 less than the units digit. if the number is divided by the sum of the digits. the quotient is 4, the remainder is 3, what is the original number?
------------
Let the original number be 10t+u
----------
Equations:
t = u - 3
(10t+u)/(t+u) = 4 + 3/(t+u)
-------------------------------
Simplify the 2nd equation:
10t+u = 4(t+u) + 3
10t+u = 4t+4u + 3
6t - 3u = 3
2t -u = 1
------------------------


Form the system of two equations:
t = u -3
2t -u = 1
----------------
Substitute to solve for "u":
2(u-3)-u = 1
2u-6-u = 1
u = 7
-------------
Substitute into t = u-3 to solve for "t":
t = 7-3 = 4
====================
The number is 47
