See a solution process below:

Explanation:

To evaluate this expression substitute:

color(red)(6) for color(red)(w)

color(blue)(0.4) for color(blue)(x)

color(green)(-3) for color(green)(z)

y is extraneous and not needed for this problem.

Substituting and calculating gives:

(5color(red)(w)color(blue)(x))/color(green)(z) becomes:

(5 xx color(red)(6) xx color(blue)(0.4))/color(green)(-3) => (30 xx color(blue)(0.4))/color(green)(-3) => 12/color(green)(-3) => -4
