Question

How do you solve `-18v = - 126`?

Answer 1

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`
