Answer:

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

Step-by-step explanation:

the equation is:

[tex]xy=k[/tex]

To find the value of [tex]x[/tex], we need to substitute the values that we know for [tex]y[/tex] and [tex]k[/tex]:

[tex]y=4[/tex]

and

[tex]k=7[/tex]

so, we substitute this values into the equation

[tex]xy=k[/tex]

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

and we clear for [tex]x[/tex], for this we move the 4 to the right dividing:

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