1. The problem is to solve the second question of q2, but since the exact question is not provided, I will assume a typical algebraic problem for demonstration. 2. Let's consider the problem: Solve for $x$ in the equation $$2x + 3 = 7$$. 3. The formula used here is to isolate $x$ by performing inverse operations. 4. Step 1: Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$. 5. Step 2: Divide both sides by 2: $$\frac{2x}{2} = \frac{4}{2}$$ which simplifies to $$x = 2$$. 6. Therefore, the solution to the equation is $x = 2$. This method applies to linear equations where the goal is to isolate the variable on one side.
