Answer:

The value of x is [tex]\frac{7}{4}[/tex].

Step-by-step explanation:

Inverse variation is defined by the equation

[tex]xy=k[/tex]

It is given that the value of y is 4 and the value of k is 7.

Substitute [tex]y=4[/tex] and [tex]k=7[/tex].

[tex]x(4)=7[/tex]

Divide both sides by 4.

[tex]\frac{4x}{4}=\frac{7}{4}[/tex]

[tex]x=\frac{7}{4}[/tex]

Therefore the value of x is [tex]\frac{7}{4}[/tex].
