1. The problem asks to solve question 4, but since the exact question is not provided, I will assume it is a typical algebraic problem involving solving an equation or expression. 2. To solve an algebraic equation, the general approach is to isolate the variable on one side of the equation using inverse operations such as addition, subtraction, multiplication, division, and factoring. 3. For example, if question 4 is to solve the equation $$2x + 3 = 7$$, we start by subtracting 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$ 4. Next, divide both sides by 2 to isolate $$x$$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ which simplifies to $$x = 2$$ 5. Therefore, the solution to the equation is $$x = 2$$. If you provide the exact question 4, I can solve it specifically.
