How do i simplify these two equations?
10w - 2(3w + 4) + 4
12x - (7y - 8x) + 4x -11y

Step-by-step explanation:

10w - 2(3w + 4) + 4 = 10w + (-2)*3w + (-2)*4 + 4

                              = 10w - 6w - 8 + 4

                             = 4w - 4

12x - (7y - 8x) + 4x - 11y = 12x - 7y + 8x +4x -11y

                                    = 12x + 8x + 4x - 7y - 11y

                                    = 24x - 18y

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
