The units digit of a two-digit number is one more than four times the tens digit. The number formed by reversing the digits is 63 larger than the original number. Find the original number.
Let tens and units digits, be T and U, respectively
Then original number is: 10T + U, and reversed number is: 10U + T
Then: U = 4T + 1 -------- eq (i)
Also, 10U + T = 10T + U + 63_____10U - U + T - 10T = 63____9U - 9T = 63_____9(U - T) = 9(7)______U - T = 7 ------- eq (ii)
Then: Substitute 4T + 1 for U in eq (ii)
Determine the value for T, the tens digit
Substitute value for T into any of the 2 equations to get the value of U
