-1/2

Step-by-step explanation:

2(5y + 3) + 4y = -1

2*5y + 2*3 + 4y = -1

  10y + 6 + 4y  = - 1       {Combine like terms}

   14y + 6 = -1                {Subtract 6 form both sides}

       14y = -1 - 6

       14y = -7             {Divide both sides by 7}

         y = -7/14

y = -1/2

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.
