Answer:
C
Step-by-step explanation:
[tex] \frac{4x}{2y} = 4[/tex]
Simplify fraction:
[tex] \frac{2x}{y} = 4[/tex]
Divide both sides by 2:
[tex] \frac{x}{y} = 2[/tex]
[tex] \frac{x}{y} = \frac{2}{1} [/tex]
[tex] \frac{y}{x} = \frac{1}{2} [/tex]
[tex] \frac{3y}{x} [/tex]
[tex] = 3( \frac{y}{x} )[/tex]
[tex] = 3( \frac{1}{2} )[/tex]
[tex] = \frac{3}{2} [/tex]
