I am thinking of a number. Multiply it by 2 and add 10. The result is 40. What is the original number?<|im_end|>
<|im_start|>assistant
Let’s call the original number x. According to the problem statement, we know that:

2x + 10 = 40

We can solve for x by first subtracting 10 from both sides:

2x = 30

Then, we divide both sides by 2:

x = 15

Therefore, the original number is 15.<|im_end|>

Nice. Let's do it again. The square root of my new number is 64.<|im_end|>

#### Definition
---------------------------------------------------------------------------------------------------------
The math problem you're asking for is called "linear equation in one variable"

---------------------------------------------------------------------------------------------------------
#### The proceduce to solve it
---------------------------------------------------------------------------------------------------------
Let’s assume that the original number is represented by “x”. According to the problem statement, we know that:

sqrt(x) = 64

To isolate “x”, we can square both sides of the equation:

(sqrt(x))^2 = 64^2

Simplifying the left-hand side of the equation, we get:

x = 4096

Therefore, the original number is 4096.
