\( \left. \begin{array} { l } { \square ^ { 8 } \square _ { 6 } | x } \\ { \frac { 8 } { 20 } = \frac { x } { 6 } \quad \frac { 20 x } { 20 } = \frac { 8 } { 2 } \cdot 5 = x = 6 } \end{array} \right. \)

It looks like you're trying to solve a proportion involving the variables \( x \) and some constants. Let's break down the equation you provided: You have the proportion: \[ \frac{8}{20} = \frac{x}{6} \] To solve for \( x \), you can cross-multiply: \[ 8 \cdot 6 = 20 \cdot x \] This simplifies to: \[ 48 = 20x \] Now, divide both sides by 20 to isolate \( x \): \[ x = \frac{48}{20} \] Simplifying \( \frac{48}{20} \): \[ x = \frac{12}{5} = 2.4 \] So, the value of \( x \) is \( 2.4 \).
