Explanation:
To find the value of y, first you have to solve this variable of y. Subtraction property is subtracting from both sides of an equation to the same number doesn't change the equation.
First, switch sides.
![\displaystyle y+10=10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/u4nheczfadeg4q2boacfnq9c8teb94qc75.png)
Next, subtract 10 from both sides.
![\displaystyle y+10-10=10-10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iz57mmd5180n3zsoxpxsho6sprbwwuxfjx.png)
Solve.
![\displaystyle 10-10=0](https://img.qammunity.org/2020/formulas/mathematics/middle-school/i068qa6943i3mfdj65xokezc80pwumhq0t.png)
As a result, the correct answer is y=0.
