desarrollar las ecuaciones CON EL PROCEDIMIENTO x FA
1. x – 4 = 12
2. 9x – 4 = 14
3. 3x = – 4
4. –2x = –14
5. 11x + 9 = −5x + 1216. 11x − 3 = −9x + 37
7. 3x + 7 = −4x – 21
8. −7x − 5 = 10x + 80
9. −3x + 9 = 2x – 26
10. 9x – 2 = 4 – 2

Respuesta :

1.

x = 12 + 4

x = 16

2.

9x = 14 + 4

9x = 18

x = 18/9

x = 2

3.

x = - 4/3

4.

(-) -2x = - 14

2x = 14

x = 14/2

x = 7

5.

11x + 5x = 121 - 9

16x = 112

x = 112/16

x = 7

6.

11x + 9x = 37 + 3

20x = 40

x = 40/20

x = 2

7.

3x + 4x = - 21 - 7

7x = - 28

x = - 28/7

x = - 4

8.

-7x - 10x = 80 + 5

(-) -17x = 85

x = -85/17

x = - 5

9.

-3x - 2x = - 26 - 9

(-) -5x = -35

x = 35/5

x = 7

10.

9x = 4 - 2 + 2

9x = 4

x = 4/9

Espero haberte ayudado. Suerte en los estudios ≧◠◡◠≦.

RESPUESTA :

1. 16

2. 2

3. -4/3

4. 7

7. -4

8. -5

9. 7

10. 4/9

Explicación paso a paso:

1 )x - 4 = 12

x= 12 + 4

x= 16

2) 9x - 4 = 14

9x = 14 + 4

9x = 18

x= 18 ÷ 9

x=2

3)

3x = - 4

3x ÷ 3 = -4 ÷ 3

x = -4 ÷ 3

x= -4/3

4)

-2x = -14

x = -14 ÷ -2

x = 7

7)

3x+7 = -4x - 21

3x + 4x + 7 = -21

3x + 4x = -21 - 7

7x = -28

x = -28 ÷ 7

x = -4

8)

-7x - 5 = 10x + 80

-7x - 10x - 5 = 80

-7x - 10x = 80 + 5

-17x = 85

x = 85 ÷ -17

x = -5

9)

-3× + 9 = 2x - 26

-3x - 2x + 9 = -26

-3x-2x = -26 - 9

-5x = -35

x = -35 ÷ 5

x = 7

10) 9x - 2 = 4 - 2

9x - 2 = 2

9x = 2 + 2

9x = 4

x = 4/9
