1. The problem is to solve the equation or expression implied by "do it". Since no specific problem is given, I will assume you want me to solve a simple algebraic example. 2. Let's solve the equation $2x + 3 = 7$. 3. The formula to isolate $x$ is to subtract 3 from both sides and then divide both sides by 2. 4. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 5. Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 6. Therefore, the solution is $x = 2$. This is a simple linear equation solving example.
