a) Given:
[tex]-x-5=5[/tex]
To solve for x:
Explanation:
Adding 5 on both sides we get,
[tex]\begin{gathered} -x-5+5=5+5 \\ -x=10 \end{gathered}[/tex]
Then, divide by -1 on both sides, we get,
[tex]\begin{gathered} \frac{-x}{-1}=\frac{10}{-1} \\ x=-10 \end{gathered}[/tex]
Thus, the value of x is -10.
Final answer:
The value of x is,
[tex]x=-10[/tex]
