To find the direct variation equation, we start with the formula for direct variation:

\[ y = kx \]

where \( k \) is the constant of variation.

From the information provided, we know that \( y = 5 \) when \( x = 55 \). We can use this to find \( k \):

\[ 5 = k \cdot 55 \]

Now, solving for \( k \):

\[ k = \frac{5}{55} = \frac{1}{11} \]

Now we can write the direct variation equation:

\[ y = \frac{1}{11}x \]

Next, we need to find the value of \( y \) when \( x = 22 \):

\[ y = \frac{1}{11} \cdot 22 \]

Calculating this, we get:

\[ y = 2 \]

So the answer is:

When x=22, y=2.
