1. Let's solve a simple algebra problem using normal terms. 2. Suppose we want to solve for $x$ in the equation $2x + 3 = 7$. 3. The formula we use is to isolate $x$ by undoing the operations around it. 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 get $x$ alone: $$\frac{2x}{2} = \frac{4}{2}$$ which simplifies to $$x = 2$$. 6. So, the solution is $x = 2$. This means if you put 2 back into the original equation, it works perfectly.
