She kayaked for 6 hours.

Step-by-step explanation:

If $10 is the initial fee, subtract $22 - $10 = $12.

If it charges $2 per hour, divide $12 by $2 which equals 6 hours.

If (2x-2) is equal to 'y', and (-x+1) is equal to 'y' then (2x-2) must be equal to (-x+1).

2x - 2 = -x + 1

Add 'x' to each side:

3x - 2 = 1

Add 2 to each side:

3x = 3

Divide each side by 3 :

x = 1

And then I guess y= 0 .
