Step-by-step explanations:
Hi there! I'm glad I was able to help you out again!
Question 1: We are given that
![x + 10 = 5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/6tcod2n2e6tjim53rw1u7n7m535xi01jkq.png)
All we have to do to solve for the unknown variable is subtract 10 from both sides of the equation, to keep things in place.
![x + 10 - 10\\= 5 - 10\\x = -5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/imjuc59welnqr8xk6t74d9833i48c16qtc.png)
We are now left with the fact that
, but just in case you are skeptical about this answer, we can always plug in our new values to the equation by replacing the variable with our answer:
![-5 + 10 = 5](https://img.qammunity.org/2021/formulas/mathematics/middle-school/75mwwgo8xnbqvyn2q6lpv3uct2g5uahbrs.png)

Question 2: We are given that
![x-3=6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/ofwgd0otj20tb6p46f1ycs3vho2ff1tts1.png)
To solve for x on this one, all we have to do is add 3 to both sides of the equation, in order to keep things neat and clean.
![x - 3 + 3\\= 6 + 3\\x = 9](https://img.qammunity.org/2021/formulas/mathematics/middle-school/tbrf1eq2riidimx2uvh5e28k75oht9cmwn.png)
Like before, in case you're confused and would like to check your answer, all you have to do is rewrite the equation as shown:
![9 - 3 = 6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/8sh8asm57ysp8vlrf7b5pzdjmj3h1jua9f.png)
You can always use a calculator if you're stuck!
I hope this helped you! :)
