Answer 1

¡MUY BUENAS TARDES sanchezmartinezelias¡

1. x +8 = 15

  x = 15 - 8

  x = 7

2. y - 1 = 11

   y = 11 + 1

   y = 12

3. 4a + 5 = 13

   4a = 13 - 5

   4a = 8

4. 7x - 11 = 10

    7x = 10 + 11

     x = 3

5. 3b + 4 = 19

   3b = 19 - 4

    3b = 15

      b = 5

6. 2x + 4 = 6

    2x = 6 - 4

    2x = 2

      x = 1

7. 4x -6 = -2

    4x = -2 +6

    4x = 4

      x = 1

8. x - 1 = -8

    x = -8 + 1

    x = -7

9. x - 5 = 5

    x = 5 + 5

    x = 10

10. - 4 + 2x = 0

     2x = 0 - 4

        x = - 4
