To solve the equation 17-3x=2, we need to isolate the variable x.

First, we can subtract 17 from both sides of the equation:
17 - 17 - 3x = 2 - 17
-3x = -15

Next, we divide both sides of the equation by -3 to solve for x:
-3x / -3 = -15 / -3
x = 5

Therefore, the solution to the equation 17-3x=2 is x = 5.
