Step by step explanation : − 4 x + 4 + x = 2 ( x + 12 ) Step 1: Simplify both sides of the equation. − 4 x + 4 + x = 2 ( x + 12 ) − 4 x + 4 + x = ( 2 ) ( x ) + ( 2 ) ( 12 ) (Distribute) − 4 x + 4 + x = 2 x + 24 ( − 4 x + x ) + ( 4 ) = 2 x + 24 (Combine Like Terms) − 3 x + 4 = 2 x + 24 − 3 x + 4 = 2 x + 24 Step 2: Subtract 2x from both sides. − 3 x + 4 − 2 x = 2 x + 24 − 2 x − 5 x + 4 = 24 Step 3: Subtract 4 from both sides. − 5 x + 4 − 4 = 24 − 4 − 5 x = 20 Step 4: Divide both sides by -5. − 5 x − 5 = 20 − 5
