#w=10#

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#
