Distribute to get 2x - 6 + 21 = -3.
Combine like terms to get 2x + 15 = -3.
Use the addition property of equality to get 2x = -3 - 15.
Simplify to get 2x = -18.
Divide both sides by 2 to solve for x: x = -9.
Distribute to get: 2x - 6 + 21 = -3
Combine like terms to get: 2x + 15 = -3
Use the addition property of equality by subtracting 15 from both sides to get: 2x = -18
Finally, divide both sides by 2 to solve for x: x = -9
