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