The inequality is .

Add 10 to each side.

Multiply each side by .

The solution set is .

Graph the solution set on a number line.

Note: A circle means that this point is not included in the solution set.

Check:

To check, substitute three different values for v into the original inequality: 56, a number less than 56, and greater than 56.

Let three values are substitute in the original inequality, .

If then      (This is false)

If then      (This is false)

If then      (This is true)

The solution set is .
