2:х=7/4

To solve the equation \( \frac{2}{x} = \frac{7}{4} \), you can cross-multiply to eliminate the fractions:

\[ 2 \cdot 4 = 7 \cdot x \]

This simplifies to:

\[ 8 = 7x \]

Next, to isolate \( x \), divide both sides by 7:

\[ x = \frac{8}{7} \]

Thus, the solution is:

\[ x = \frac{8}{7} \]
