First a note to tutor ikleyn. You have stated many times that English is not your first language; and often the awkward language you use in your responses shows it. You are not in a good position to criticize the language used in the questions students post.
To the person who posted the question: Since this is a linear equation, containing both x and y variables, there will be exactly one x intercept and one y intercept. However, grammatically it is still valid to ask for the coordinates of "any" intercepts.
And now to the math itself....
By definition, an x intercept is where the y value is 0; a y intercept is where the x value is 0. So in any equation (linear or not) where you are looking for x intercepts, set y=0 in the equation; and where you are looking for y intercepts, set x=0 in the equation.
For your example, to find the x intercept, set y=0 and solve:
The x intercept is 6, or (6,0).
To find the y intercept, set x=0 and solve:
The x intercept is 20, or (0,20).
