Distribute across parentheses.
Combine the* x*-values.
Subtract 12 from both sides.
Divide both sides by 2.
*Note: *There was no multiplication or division by a negative value, so the inequality symbol did not get reversed.
*Remember*: -1 < *x* can be **reversed** so *x* is on the left side, and written as *x* > -1.
