Answer:

x=4

Explanation:

To solve for x, we need to isolate it.

Start by adding 16 to each side to cancel out the -16:

-x=-4

-x is essentially -1 * x which can be written as -1x

-1x=-4

Divide both sides by -1 to isolate x

x=4

We can also plug this back into the equation to check:

-16-x=-20

-16-4=-20

-20=-20 --> correct!
