Step 1: Distribute to get
Step 2: Combine like terms to get
Step 3: Use
to get 2x=−18
Step 4: Use
to get x=−9
Step 1: Distribute to get 2x - 6 + 21 = -3
Step 2: Combine like terms to get 2x + 15 = -3
Step 3: Use subtraction to get 2x = -18
Step 4: Use division to get x = -9
Step 1: Distribute to get 2x - 6 + 21 = -3
Step 2: Combine like terms to get 2x + 15 = -3
Step 3: Use subtraction to isolate the variable: 2x = -3 - 15, which simplifies to 2x = -18
Step 4: Divide both sides by 2 to solve for x: x = -18/2, which simplifies to x = -9
