Span of a set of 3D vectors

  1. 1. Given b = (-2,3,7), u1= (4,-1,5) and u2= (3,1,3) and u3 = (5,02), determine if vector b is in the span of the remaining vectors



    2. Relevant equations



    3. You just solve for three equations with three unknowns? -2x + 4y + 3z = 5, 3x - y + z = 0, 7x + 5y + 3z = 2

    Those are the equations to determine if u3 is in the span of b, u1 and u2. Which is not quite the same question.
