A student solves the inequality −5v>55. Each step in the student's solution is shown below. Identify where the student made any errors.

Answer 1

Note: Steps of student are not given. So, the proper steps of the solution are provided below.

Given:

The inequality is

`-5v>55`

To find:

Where the student made any errors?

Solution:

We have,

`-5v>55`

On dividing both sides -5 change the sign of equality because -5 is a negative number.

`(-5v)/(-5)<(55)/(-5)`

`v<-11`

Therefore, the solution of given inequality is
`v<-11`.
