Answer 2

Answer: second option.

Explanation:

Let be "x" the unknown number.

According to the information provided in the exercise, 10 is the result of the subtraction of "x" and -5.

Based on this, you can write the following equation:

`x-(-5)=10`

To find the value of "x" you must remember the multiplication of signs:

`(+)(+)=+\\(-)(-)=+\\(-)(+)=-`

Then:

`x-(-5)=10\\\\x+5=10`

Finally, subtracting 5 from both sides of the equation, you get:

`x+5-(5)=10-(5)\\\\x=5`
