Step 2: **Find the constant \(k\)** Given \(x = 3\) and \(y = 12\): \[3 \times 12 = k\] \[k = 36\] Step 3: **Write the equation** Using the constant \(k\), the equation is: \[x \cdot y = 36\] Step 4: **Solve for \(x\)** \[x = \frac{36}{y}\] Click to rate:98.1(582 votes)Search questionBy textBy image/screenshotDrop your file here orClick Hereto upload
