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.
