Answer
$x \approx 3.4$
Work Step by Step
To solve a proportion, we use the cross products property, multiplying the numerator of one ratio with the denominator of the other ratio, and vice versa:
$4(6) = 7x$
Multiply on the left side of the equation:
$24 = 7x$
Divide each side of the equation by $7$ to solve for $x$:
$x \approx 3.4$
