sketch errors. over constraining and redundant - beginner help

Where can I find good explanations about over constraining and redundant? I cant get my sketch fully defined with dimensions without errors, when I success at fixing one error, right after I got another error, I need to learn how its working exactly. 
For example, how do I change the yellow dimension without getting an error? should I need to change both 6.4 dimensions for it to work? its really confusing

    You don't need the yellow dimension as, I'm guessing that you have a symmetrical constraint and your mid point of the yellow dimension is in line with the origin so the 96 is defined by the 21.1 and the 26.5 dimensions.

    Can I suggest doing the Onshape self paced courses?



    Just a quick way to do it differently.
    Mostly defined around the centre. No more dims required.

    harel_barak952 , Good advice above, and I would add.
    To obtain speed and efficiency while sketching you should always ask yourself if your part has symmetry. If it is a round part - only draw half of the profile, then revolve (this saves time while sketching and placing dimensions)  If you are working on a specific tutorial, then this advice may not apply. But it is still good practice to follow this rule on your other work.
     If you are looking for practice, I would suggest taking a project you have done before, and starting from scratch, do it again - trying to reduce the number of steps, or eliminate some complexity from sketches. In other words, completing it faster. Discovering ways to speed-up your modeling technique usually gives a "best practice" type scenario.
    Keep at it, and good luck.
