me ayudan????????????​

Answer 1

Respuesta:

2x + 7 = -3

     2x = -3 - 7

     2x = -10

       x = -10 / 2

      x = -5

5x + -7 = x - -9

5x - 7 = x + 9

5x - x = 9 + 7

    4x = 16  

      x = 16 / 4

      x = 4

-9 + 6x = 15 + 2x

6x - 2x = 15 + 9

      4x = 24

        x = 24 / 6

        x = 6

5x - 1 = 9

   5x = 9 + 1

   5x = 10

     x = 10 / 5

     x = 2
