Answer: D) subtraction

Explanation:

The given equation:
2x+5=10

To solve this equation for the value of x, first we need to remove 5 from the left side.

For this we need to first subtract 5 from both the sides of the equation.

The equation will become
2x+5-5=10-5

$\\\Rightarrow2x=10$

Then , we need to remove 2 from the left side to get the value of x, so we divide 2 from the both sides, we get

x=5
