Let's evaluate each expression step by step:<br /><br />1. \(12 - x\):<br /> \[<br /> 12 - 9 = 3<br /> \]<br /> So, \(12 - x = 3\).<br /><br />2. \(x + 3y\):<br /> \[<br /> 9 + 3 \cdot 6 = 9 + 18 = 27<br /> \]<br /> So, \(x + 3y = 27\).<br /><br />3. \(4y - 10\):<br /> \[<br /> 4 \cdot 6 - 10 = 24 - 10 = 14<br />, \(4y - 10 = 14\).<br /><br />4. \(\frac{1}{3}xy\):<br /> \[<br /> \frac{1}{3} \cdot 9 \cdot 6 = \frac{1}{3} \cdot 54 = 18<br /> \]<br /> So, \(\frac{1}{3}xy = 18\).<br /><br />Now, let's match each expression to its value:<br /><br />- \(12 - x = 3\)<br />- \(x + 3y = 27\)<br />- \(4y - 10 = 14\)<br />- \(\frac{1}{3}xy = 18\)<br /><br />So the final matching is:<br /><br />- \(12 - x\) matches with \(3\)<br />- \(x + 327\)<br />- \(4y - 10\) matches with \(14\)<br />- \(\frac{1}{3}xy\) matches with \(18\)
