im really confused on this please help if you can

Answer:
A. 2[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
You have to replace x with one of the values in the set. You have to find the one that works.
3[tex]\frac{1}{2}[/tex]x = 8[tex]\frac{3}{4}[/tex]
8[tex]\frac{3}{4}[/tex] ÷ 3[tex]\frac{1}{2}[/tex] = x
8[tex]\frac{3}{4}[/tex] ÷ 3[tex]\frac{1}{2}[/tex] = 2[tex]\frac{1}{2}[/tex]
Hope this helps :)
