y varies inversely as three times x. When x = 6, y = 4. Find x when y = 8

OpenStudy (pfenn1):

If y varies inversely as three times x, you have an equation \[y=\left( k \over 3x \right)\] where k is a constant to be determined. Does this make sense?

OpenStudy (pfenn1):

We know when x=6, y=4, so plug these values into the equation and solve for k.
