Let's solve the equation [tex]\(1 - 2x - 1 = -10\)[/tex] step by step.

Firstly, simplify the left-hand side of the equation:

[tex]\[1 - 2x - 1 = -10\][/tex]

Notice that [tex]\(1 - 1\)[/tex] simplifies to 0, so we are left with:

[tex]\[-2x = -10\][/tex]

Next, we want to solve for [tex]\(x\)[/tex]. To do this, we need to isolate [tex]\(x\)[/tex]. Divide both sides of the equation by [tex]\(-2\)[/tex]:

[tex]\[ x = \frac{-10}{-2} \][/tex]

Simplify the fraction:

[tex]\[ x = 5 \][/tex]

Therefore, the solution to the equation [tex]\(1 - 2x - 1 = -10\)[/tex] is [tex]\(x = 5\)[/tex].

So, the correct answer is:

B. [tex]\(x = 5\)[/tex]
