Hey there!

To solve, let's first add 5 to both sides.

xy=k+5

Now we divide both sides by y.

x=
(k+5)/(y)

I hope this helps!

Hey there! :)

xy - 5 = k

We need to isolate x, so we can start out by adding 5 to both sides.

xy - 5 + 5 = k + 5

Simplify.

xy = k + 5

Now, we can simply divide both sides by y.

xy ÷ y = k + 5 ÷ y

Simplify.


x = (k + 5)/(y)

~hope I helped~
