To solve for \( x \) in the equation \( 4x = 6 \), you can divide both sides by 4:
\[ x = \frac{6}{4} \]
Simplifying \( \frac{6}{4} \) gives \( \frac{3}{2} \) or \( 1.5 \).
In the provided options, \( 1 and 1 half \) (which is also written as \( \frac{3}{2} \)) matches this result.
Therefore, the value of \( x \) is \( 1 and 1 half \).
