1(x + 3) + 3(x - 1) = 20
1(x) + 1(3) + 3(x) - 3(1) = 20
               x + 3 + 3x - 3 = 20
               x + 3x + 3 - 3 = 20
                                4x = 20
                                 4      4
                                  x = 5

Therefore, there are 15 grams of cocoa in the chocolate bar.
