Beyond the Answer
To solve the equation \( -\frac{1}{3} y + 6 = 5 \), you can start by isolating \( y \). First, subtract 6 from both sides to get \( -\frac{1}{3} y = 5 - 6 \). This simplifies to \( -\frac{1}{3} y = -1 \). Now, to eliminate the negative sign and the fraction, multiply both sides by -3: \( y = (-1) \cdot (-3) \) which gives you \( y = 3 \). So, the solution to the equation is \( y = 3 \). The double number line can visually represent the relationship and help trace these changes step-by-step, making it easier to see how the equation balances out.
