The correct Answer is:
To solve the given system of equations: 1. **First Equation:** \[ x + \frac{6}{y} = 6 \] We can rearrange this equation to express it in terms of \(y\): \[ x = 6 - \frac{6}{y} \] To eliminate the fraction, we can multiply through by \(y\) (assuming \(y \neq 0\)): \[ xy + 6 = 6y \] Rearranging gives us: \[ xy - 6y + 6 = 0 \quad \text{(Equation 1)} \] 2. **Second Equation:** \[ 3x - \frac{8}{y} = 5 \] Similarly, we rearrange this equation: \[ 3x = 5 + \frac{8}{y} \] Again, multiplying through by \(y\): \[ 3xy - 8 = 5y \] Rearranging gives us: \[ 3xy - 5y - 8 = 0 \quad \text{(Equation 2)} \] 3. **Now we have two equations:** - Equation 1: \(xy - 6y + 6 = 0\) - Equation 2: \(3xy - 5y - 8 = 0\) 4. **Next, we can eliminate \(xy\) by manipulating the equations.** We can multiply Equation 1 by 3: \[ 3(xy - 6y + 6) = 0 \implies 3xy - 18y + 18 = 0 \] This gives us: \[ 3xy - 18y + 18 = 0 \quad \text{(Equation 3)} \] 5. **Now, we can subtract Equation 2 from Equation 3:** \[ (3xy - 18y + 18) - (3xy - 5y - 8) = 0 \] Simplifying this: \[ -18y + 5y + 18 + 8 = 0 \] This simplifies to: \[ -13y + 26 = 0 \] Solving for \(y\): \[ -13y = -26 \implies y = 2 \] 6. **Now that we have \(y\), we can substitute it back into Equation 1 to find \(x\):** \[ x + \frac{6}{2} = 6 \] Simplifying gives: \[ x + 3 = 6 \implies x = 3 \] 7. **Final Solution:** \[ x = 3, \quad y = 2 \]
