    Let's solve your equation step-by-step. x - (9x - 10) + 11 = 12x + 20 - 2 Step 1: Simplify both sides of the equation. x - (9x - 10) + 11 = 12x + 20 - 2 Simplify: (Hide steps) x + - 9x + 10 + 11 = 12x + 20 + - 2 (x + - 9x) + (10+11) = (12x) + (20 + - 2) (Combine Like Terms) - 8x + 21 = 12x + 18 - 8x + 21 = 12x + 18 Step 2: Subtract 12x from both sides. - 8x + 21 - 12x = 12x + 18 - 12x - 20x + 21 = 18 Step 3: Subtract 21 from both sides. - 20x + 21 - 21 = 18-21 - 20x = - 3 Step 4: Divide both sides by - 20. - 20x - 20 = - 3 - 20 x = 320 Answer: x = 3 20
