Answer

{-14}.

Work Step by Step

x-3= -17 Step 1: Add 3 on both the sides x-3+3 = -17+3 Step 2: Simplify x= -14 Now we check the proposed solution, -14, by replacing x with -14 in the original equation. Step 1: the original equation x-3 =-17 Step2: Substitute -14 for x -14 - 3 = -17 Step 3: Add -14 - 7 = -17 -17 = -17 Since the check results in true statement, we conclude that the solution set of the given equation is {-14}.
