Let the digits be a, and b.
Your number is x.
x = 10 a + b
My tens digit is double of my ones digit means:
a = 2 b
Now:
The sum of my digit is nine means:
a + b = 9
Replace a with 2 b in this equation.
2 b + b = 9
3 b = 9
b = 9 / 3
b = 3
a = 2 b = 2 ∙ 3 = 6
x = 10 a + b
x = 10 ∙ 6 + 3 = 60 + 3 = 63
Your number is 63
Your number is x.
x = 10 a + b
My tens digit is double of my ones digit means:
a = 2 b
Now:
The sum of my digit is nine means:
a + b = 9
Replace a with 2 b in this equation.
2 b + b = 9
3 b = 9
b = 9 / 3
b = 3
a = 2 b = 2 ∙ 3 = 6
x = 10 a + b
x = 10 ∙ 6 + 3 = 60 + 3 = 63
Your number is 63
