1. Let's state the problem: We want to solve an algebraic problem using a simple method. 2. The simple method often involves isolating the variable on one side of the equation. For example, if the problem is $ax + b = c$, we use the formula $x = \frac{c - b}{a}$. 3. Important rules: - You can add or subtract the same number from both sides of the equation. - You can multiply or divide both sides by the same nonzero number. 4. Let's apply this to a sample problem: Solve $3x + 4 = 19$. 5. Subtract 4 from both sides: $3x + 4 - 4 = 19 - 4$ which simplifies to $3x = 15$. 6. Divide both sides by 3: $\frac{3x}{3} = \frac{15}{3}$ which simplifies to $x = 5$. 7. So, the solution is $x = 5$. This method is straightforward and works for linear equations.
