1. The problem is to solve a basic math question, but since no specific question was provided, let's consider a simple example: Solve for $x$ in the equation $2x + 3 = 7$. 2. The formula used here is to isolate $x$ by performing inverse operations. 3. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 4. Divide both sides by 2 to solve for $x$: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 5. Therefore, the solution is $x = 2$. This method applies to simple linear equations where you perform inverse operations to isolate the variable.
