In an earlier paper, for ‘large’ (but otherwise unspecified) subsets , , , of q, Sárközy showed the solvability of the equations a + b = cd with a, b, c, d. This equation has been studied recently by many other authors. In this paper, we study the solvability of systems of equations of this type using additive character sums.
