What is the solution for x-y=1 and x=1/2y+2 in Solving Systems Using Substitution?



      x - y = 1  , x = 1/2y + 2



     1/2y + 2 - y = 1

            -1/2y = -1

                y = 2



    

     x = 1/2y + 2

       = 1/2(2) + 2

       = 3



Checking



        x - y = 1

        3 - 2 = 1

            1 = 1 --- true



      x = 1/2y + 2

      3 = 1/2(2) + 2

      3 = 1 + 2

      3 = 3 ---------> True





therefore x = 3 and y = 2
