1. To solve the expression or equation, first identify the problem statement clearly. 2. Perform algebraic manipulations such as expanding brackets, combining like terms, or simplifying fractions as required. 3. Substitute known values and simplify step-by-step using arithmetic operations. 4. Keep each intermediate step clearly written with the resulting simplified form. 5. Conclude with the final simplified value or expression. (If you provide a specific problem, I can give you the detailed step-by-step calculation directly.)
