ecuaciones
1) 4x + 1 =2

2) 5x + 6 = 10x + 5

3) 5x - 9 = 3x + 17

4) 11x + 5x - 1 = 65x - 36

5) 8x - 4 + 3x = 7x + x + 14

6) 8x + 9 - 12x = 4x - 13 - 5x

7) 3x + 101 - 4x - 33 = 100 - 16x - 100

8) 14 - 12x + 39x - 18x = 256 - 60x - 657x

Alguien me ayuda? :c​

Answer 1

Respuesta:

1) 4x + 1 =2

4x = 1

x = 1/4

2) 5x + 6 = 10x + 5

6-5 = 10x - 5x

1 = 5x

1/5 = x

3) 5x - 9 = 3x + 17

2x = 26

x= 13

4) 11x + 5x - 1 = 65x - 36

16x - 1 = 65x - 36

35 = 49x

5/7 = x

5) 8x - 4 + 3x = 7x + x + 14

11x - 4 = 8x + 14

3x = 18

x = 6

6) 8x + 9 - 12x = 4x - 13 - 5x

-4x + 9 = -x - 13

22 = 3x

22/3 = x

7) 3x + 101 - 4x - 33 = 100 - 16x - 100

-x + 68 = -16x

15x = -68

x -68/15

8) 14 - 12x + 39x - 18x = 256 - 60x - 657x

9x + 14 = 256 - 717x

726x = 242

x = 1/3
