Question 1157360: The units digit of two-digit number exceeds the tens digit by 2. Find the number if it is four times the sum of its digits. Answer by VFBundy(438) (Show Source):
You can put this solution on YOUR website! Tens digit = t
Units digit = t + 2
10t + (t + 2) = 4(t + (t + 2))
10t + t + 2 = 4(t + t + 2)
11t + 2 = 4(2t + 2)
11t + 2 = 8t + 8
3t = 6
t = 2
Tens digit = t = 2
Units digit = t + 2 = 2 + 2 = 4 The number is 24.
