Answer:

Step-by-step explanation:

-x - 7 = -14

Add 7 (additive inverse of -7) to both sides

-x - 7 + 7 = -14 + 7

-x = -7    

Divide both sides by -1

-x/-1 = -7/-1

x = 7

Check: Left Hand Side = -x - 7   {Substitute the value of x}

                                     = -7 - 7

                                     = - 14 = RHS
