2. 3x + 7 = 22

3. 2x – 1 = 5

4. 4x – 2 = 6

con el procedimiento

Answer 1

Respuesta:

1. 2x + 9 = 19

11x = 19

x = 19/11

x = 1,7

2. 3x + 7 = 22

10x = 22

x = 22/10

x = 2,2

3. 2x - 1 = 5

1x = 5

x = 5/1

x = 5

4. 4x - 2 = 6

2x = 6

x = 6/2

x = 3

Listo ^^

Answer 2

Explicación paso a paso:

• 2x + 9 = 19

2x = 19 – 9

2x = 10

x = 10/2

x = 5

• 3x + 7 = 22

3x = 22 – 7

3x = 15

x = 15/3

x = 5

• 2x – 1 = 5

2x = 5 + 1

2x = 6

x = 6/2

x = 3

• 4x – 2 = 6

4x = 6 + 2

4x = 8

x = 8/4

x = 2
