when a number is added or subtracted with its double gives you 4 by 12.what are the numbers?

what is 4 by 12?

To find the numbers when a number is added or subtracted by its double that gives 4 by 12, we can set up equations and solve for the unknown numbers.

Let's assume the number is "x". According to the given condition, when the number "x" is either added or subtracted by its double, the result is 4 by 12, which can be simplified to 1 by 3 or 1/3.

Now, we can set up two equations based on the given conditions:

1) x + 2x = 1/3 (when the number is added by its double)
2) x - 2x = 1/3 (when the number is subtracted by its double)

Solving the first equation:
Combining like terms, we get:
3x = 1/3
Dividing both sides by 3, we find:
x = 1/9

Solving the second equation:
Combining like terms, we get:
-x = 1/3
Multiplying both sides by -1 to isolate x, we find:
x = -1/3

Therefore, the two numbers that satisfy the given condition are 1/9 and -1/3.
