w=10

Explanation:

Solve for w.

-10-18w=-19w

Add -18w on both sides so the nonvariable (-10) would be isolated.

-10-18w+18w=-19w+18w

-10=-w

Note: -w also means -1w.

Now, divide -1 on both sides of the equation.
-10/-1=-w/-1

We would cancel, and a negative divided by a negative would be a positive so:
10=w
