1. The problem asks to answer all questions in the image, but since only the first question is to be solved, we focus on that. 2. Without the image, we assume a typical algebraic problem such as solving an equation or simplifying an expression. 3. For example, if the first question is to solve $2x + 3 = 7$, we proceed as follows: 4. Start with the equation: $2x + 3 = 7$ 5. Subtract 3 from both sides: $$2x + \cancel{3} - 3 = 7 - 3$$ which simplifies to $$2x = 4$$ 6. Divide both sides by 2: $$\frac{2x}{\cancel{2}} = \frac{4}{2}$$ which simplifies to $$x = 2$$ 7. The solution is $x = 2$. 8. This method applies to linear equations: isolate the variable by performing inverse operations step-by-step.
