{-26}

x+12 = -14 Step 1: subtract 12 from both the sides x+12 -12 = -14-12 Step 2: Simplify x= -26 Now we check the proposed solution, -26, by replacing x with -26 in the original equation. Step 1: the original equation x+12 =-14 Step2: Substitute -26 for x -26 +12 = -14 Step 3: Solve -26 + 12= - 14 -14 = -14 Since the check results in true statement, we conclude that the solution set of the given equation is {-26}.
