Question

How do you solve `\frac { - 1+ v } { 3} = - 7`?

Answer 1

`v=-20`

Explanation:

By simplifying the equation:

`(-1+v)/3=-7`
`((-1+v)/3)xx3=-7xx3`------> multiply by 3 both sides
`((-1+v)/cancel3)xxcancel3=-7xx3`
`-1+v=-21`
`-1+v+1=-21+1`-----> adding 1 both sides to make `v` the subject
`v=-20`
