3x-27

What would you like to do with the expression 3x - 27? Here are common options:

• Factor: 3x - 27 = 3(x - 9)
• Solve for x when equal to zero: 3x - 27 = 0 → x = 9
• Solve for x when it equals some number b: 3x - 27 = b → x = (b + 27) / 3 = b/3 + 9
• If you have an inequality, e.g., 3x - 27 > 0, then x > 9
