w=0

Simplifying 2(w + -3) + 6 = 0 Reorder the terms: 2(-3 + w) + 6 = 0 (-3 * 2 + w * 2) + 6 = 0 (-6 + 2w) + 6 = 0 Reorder the terms: -6 + 6 + 2w = 0 Combine like terms: -6 + 6 = 0 0 + 2w = 0 2w = 0 Solving 2w = 0 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Divide each side by '2'. w = 0 Simplifying w = 0
