Explanation:
You can observe in the exercise that the equation you need to solve is:
![x-5=10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/s7aicmahjhugwt6n5pj94oc20vpv17szol.png)
You need to find the value of the variable "x" of this equation. To do this, you need to remember the Addition Property of equality, which states that:
![If\ a=b\ then\ a+c=b+c](https://img.qammunity.org/2020/formulas/mathematics/middle-school/htcg9p97dq0uci4f5r9pcvvfor3w46vw4a.png)
Knowing this, to solve for the variable "x", you must add 5 to both sides of the equation. Therefore, you get this result:
![x-5+5=10+5\\x=15](https://img.qammunity.org/2020/formulas/mathematics/middle-school/x7wgfngfhmqxaj8fvb76yjx57fs8aex7iq.png)
