1. The problem asks how to solve part B, but since the original question is not provided, I will explain a general approach to solving algebraic problems labeled as B. 2. Typically, part B might involve solving an equation or simplifying an expression. The first step is to clearly write down the equation or expression. 3. Use algebraic rules such as combining like terms, applying distributive property, and isolating the variable. 4. If the problem involves fractions, multiply both sides by the least common denominator to clear fractions. 5. Always show intermediate steps, for example, if dividing both sides by a factor, use \cancel{} to indicate cancellation. 6. After simplification, solve for the variable by isolating it on one side. 7. Check your solution by substituting back into the original equation. Since the exact problem B is not given, this is a general method to approach such problems. Please provide the specific problem for a detailed solution.
