  1. Sketch your three intersecting circles, V, B, and T
    place 20, 10 and 6 in the "only" part of the circles.
    Place 4 in the intersection of all circles.
    Place x in the remaining parts of the circle.
    Add up all the parts:
    x + x + x + 4 + 20 + 10 + 6 = 70
    3x + 40 = 70
    3x = 30
    x = 10

    Now you know all parts of the different circles
