    5x + 15 = 28 |subtract 15 from both sides

    5x = 13 |divide both sides by 5

    x = 13/5

    x = 2 3/5

    x = 2.6

    Simplifying (5x + 15) = 28 Reorder the terms: (15 + 5x) = 28 Remove parenthesis around (15 + 5x) 15 + 5x = 28 Solving 15 + 5x = 28 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + - 15 + 5x = 28 + - 15 Combine like terms: 15 + - 15 = 0 0 + 5x = 28 + - 15 5x = 28 + - 15 Combine like terms: 28 + - 15 = 13 5x = 13 Divide each side by '5'. x = 2.6 Simplifying x = 2.6
