Need help with translations question

The following transformations take place on the y = tan x graph.

1. A stretch parallel to the x axis of scale factor 3
2. A translation 10 degrees in the positive x direction
3. A translation 2 units in the negative y direction

I got the answer y = tan (1/3x - 10/3) -2

However the answer states y = tan (1/3x - 10) - 2

I calculated my answer by doing
1. y = tan 1/3x
2. y = tan 1/3(x-10) - 2

I can't understand why this answer is wrong, could somebody please help me. Thanks
