When negative five is subtracted from a number the result is 10 find the number

levacccp [35]

Answer: second option.

Step-by-step 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:

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