The image contains several algebraic rational expressions involving addition and subtraction. To simplify or solve these, the steps typically involve:

1. Identifying common denominators for all terms in each expression.
2. Rewriting the fractions with the common denominator.
3. Combining the numerators while keeping the common denominator.
4. Simplifying the result, if possible.

Let me know which specific question you would like to start with (e.g., $o$, $p$, $q$, etc.), or if you'd like a step-by-step solution for all.
