    Simplifying 3 (4x + - 5) + 4 (2x + 6) = 0

    Reorder the terms: 3 (-5 + 4x) + 4 (2x + 6) = 0 (-5 * 3 + 4x * 3) + 4 (2x + 6) = 0 (-15 + 12x) + 4 (2x + 6) = 0

    Reorder the terms: - 15 + 12x + 4 (6 + 2x) = 0 - 15 + 12x + (6 * 4 + 2x * 4) = 0 - 15 + 12x + (24 + 8x) = 0

    Reorder the terms: - 15 + 24 + 12x + 8x = 0

    Combine like terms: - 15 + 24 = 9 9 + 12x + 8x = 0

    Combine like terms: 12x + 8x = 20x 9 + 20x = 0 Solving 9 + 20x = 0

    Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + - 9 + 20x = 0 + - 9

    Combine like terms: 9 + - 9 = 0 0 + 20x = 0 + - 9 20x = 0 + - 9

    Combine like terms: 0 + - 9 = - 9 20x = - 9

    Divide each side by '20'. x = - 0.45

    Simplifying x = - 0.45
