Let's dive into this system of equations! To begin solving, we notice that \(x\) has two values: 5 and 7. That means we can plug each \(x\) value into the corresponding equation to find \(y\). For \(x = 5\): 1. Substitute \(5\) into the second equation: \(4(5) - 4y = 12\) \(20 - 4y = 12\) \(20 - 12 = 4y\) \(8 = 4y\) \(y = 2\). For \(x = 7\): 2. Substitute \(7\) into the second equation: \(3(7) + 5y = 25\) \(21 + 5y = 25\) \(5y = 25 - 21\) \(5y = 4\) \(y = \frac{4}{5}\). So the solutions are: 1. For \(x = 5\), \(y = 2\) (so the point is (5, 2)). 2. For \(x = 7\), \(y = \frac{4}{5}\) (so the point is (7, 0.8)). Now you have two distinct points!
