me ayudan con esto porfavor ​

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 - 7 = x + 9

5x - x = 9 + 7

4x = 16

x = 16/4

x = 4

• -9 + 6x = 15 + 2x

6x - 9 = 15 + 2x

6x - 2x = 15 + 9

4x = 24

x = 24/4

x = 6

• 5x - 1 = 9

5x - 1 = 9

5x = 9 + 1

5x = 10

x = 10/5

x = 2

• 4x - 2 = 8 + 3x

4x -2 = 8 + 3x

4x - 3x = 8 + 2

x = 10

• -6 + 2x - 5 = 5x + 10 - 3

2x - 6 - 5 = 5x + 10 - 3

2x - 11 = 5x + 7

2x - 5x = 7 + 11

-3x = 18

x = 18/-3

x= -6

• 8 + 12x = 15x - 19

12x + 8 = 15x - 19

12x - 15x = -19 - 8

- 3x = -27

x = -27/-3

x = 9

• x/4 = 100

x = 100 × 4

x = 400
