solve for x.

-10 - 2x = -8
a x = 4
b x = 1
c x = 9
d x = -1

To solve for x in the equation -10 - 2x = -8, we can start by adding 10 to both sides of the equation:

-10 - 2x + 10 = -8 + 10

This simplifies to:

-2x = 2

Next, divide both sides of the equation by -2:

(-2x) / -2 = 2 / -2

This simplifies to:

x = -1

Therefore, the solution is d) x = -1.
