Question

7+4+x-6=5+4

12-8+y-3=21+4

3+2a-8-5=25+3
ayuda porfavor

Answer 1

7 + 4 + x - 6 = 5 + 4

      13 + x - 6 = 9

        7 + x = 9

          x = 2

__________________________________

12 - 8 + y - 3 = 21 + 4

     4 + y - 3 = 25

       y - 3 = 21

         y = 24

__________________________________

3 + 2a - 8 - 5 = 25 + 3

        3 + 2a - 3 = 28

        3 + 2a = 31

         2a = 28

          a = 14
