1. Let's start with a simple math problem to teach you how to solve it step-by-step. 2. Suppose we want to solve the equation $2x + 3 = 7$ for $x$. 3. The formula to isolate $x$ is to get $x$ alone on one side of the equation by performing inverse operations. 4. First, subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ which simplifies to $$2x = 4$$. 5. Next, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{4}{2}$$ which simplifies to $$x = 2$$. 6. So, the solution to the equation $2x + 3 = 7$ is $x = 2$. 7. This method works for many linear equations: perform inverse operations step-by-step to isolate the variable. 8. If you want to learn more or try other problems, just ask!
