Answer:

x = 55

Step-by-step explanation:

given x varies inversely as x then the equation relating them is

x = \frac{k}{y} ← k is the constant of variation

to find k use the given condition x = 11 when y = 3

k = xy = 11 × 15 = 165

x = \frac{165}{y} ← variation equation

when y = 3, then

x = \frac{165}{3} = 55
