Let a be the number
And b be the other number.
a is twice the other number means you add b two times or multiply it by two, 2b
a is also 5 more than the above, that is you add 5 to 2b, a=5+2b .......(1)
The sum of the two numbers means (a+b) and that is equal to 29, that is; a+b=29 ......(2)
Substituting the value of a (or b will also work) in (2), we get:
5+2b+b=29
5+3b=29
3b=29-5=24
b=24/3=8
Now that we have the value of b, and since a+b=29, then:
a+8=29
a=29-8
a=21
The answer: a=21, b=8
To prove 21 is 5 more than twice 8, which is 16.
