Let the tens digit be x, and ones digit be y. So we have:
x + y = 12
x = y + 2
Substitute y + 2 for x to the first equation:
x + y = 12
(y + 2) + y = 12
y + y + 2 - 2 = 12 - 2
2y = 10
2y/2 = 10/2
y = 5 the ones digit
y + 2 = 5 + 2 = 7 the tens digit
Thus, the number is 75.

What is the two digit numeral whose units' digit is 5 more than its tens digit and whose value equals 3 times the sum of these digits?
27. Let the first (tens) digit be x. Then, since the units digit is the tens digit plus 5, the second (units) digit is (x + 5) and the number is: 10x + (x + 5) = 11x + 5. And 3 times the sums of its digits is: 3(x + (x + 5)) = 3(2x + 5) = 6x + 15 But this is equal to the number, so: 11x + 5 = 6x + 15 ⇒ 5x = 10 ⇒ x = 2 ⇒ (x + 5) = (2 + 5) = 7 So the number is 27. Checking: 3 x (2 + 7) = 3 x 9 = 27

The sum of the digits in two- digit number is 15 If the number is 6 more than 15 times the units digit find the number?
If the sum of the digits in a two-digit number is 15, and the number is 6 more than 15 times the units digit, the number is 96. Let A and B be the digits. (A is the tens digit and B is the units digit) A + B = 15, therefore A = 15 - B 10A + B = 15B + 6Substituting for A, and solving for B...10(15 - B) + B = 15B + 6150 - 10B + B = 15B + 6150 - 9B = 15B + 6144 - 9B = 15B144 = 24BB = 6 Back substitute B into first equation and solve for A...A + 6 = 15A = 9 Therefore, the digits are 9 and 6, so the number is 96.

The number obtained by reverting the digits is 594 less than the original number the number is?
There are 40 possible answers. There can be any digit in the tens place. The digit in the hundreds place must be 6 more than the one in the units place.
What number am I My tens digit is the lowest even number my hundreds digit is six more than my tens digit and my one digit is one more than my tens digit my thousands digit is the second odd number?

The ten's digit of a two-digit number is 3 more than the units' digit The number is 8 more than six times the sum of the digits Find the number?
Let x be the unknown number and let y be the ten's digit,then x = 10y + y - 3 = 11y - 3,and x = 8 + 6(y + y - 3) = 8 + 6(2y - 3) = 8 + 12y - 18 = 12y -10,therefore 12y - 10 = 11y - 3.Subtracting 11y and adding 10 to each side, y = 7.Since the ten's digit is 7, the unit's digit must be 4, and the number is 74.
What is the greatest six digit even number where the ten thousand digit is twice tens digit hundred thousand digit is more than 6 the thousands digit is divided by ones digit and no digit repeated?
In order to get the greatest number we want to try and get the biggest possible numbers in the hundred thousands, ten thousands and thousand places. There is no rule against the hundred thousands digit being 9 so it must be 9. The ten thousand digit needs to be twice the tens so it must be 8 while the tens is 4. The thousands digit is divided by the units, and the number is even. So thousands must be 6 and the units must be 2. Thus the hundreds must be 7. The number is 986,742
