See down below.

Explanation:

The equation is

#-18v = -126#

and we have to solve for #v#. We have to get #v# by itself, so we have to divide by #-18# to cancel out the multiplication. Division and multiplication cancel each other out and addition and subtraction cancel each other out.

Since we divided by #-18# on one side, we have to do it on the other as well. When we divide #-126# by #-18#, we get #7#. When you multiply or divide two negative numbers, it turns to a positive number.

#v=7#
