Answer: D) subtraction
Step-by-step explanation:
The given equation: [tex]2x+5=10[/tex]
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 [tex]2x+5-5=10-5[/tex]
[tex]\\\Rightarrow2x=10[/tex]
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
[tex]x=5[/tex]
