Answer 1

Explicación paso a paso:

1) x - 7 = 0

x = 7

2) x + 5 = - 3

x = - 3 - 5

x = - 8

3) y - 3 = 11

y = 11 + 3

y = 14

4) - x + 4 = 9

-x = 9 - 4

x = - 5

5) 3 - z = 2

-z = 2 - 3

-z = - 1

z = 1

6) 11 = z + 3

11 - 3 = z

8 = z

7) 2x + 6 = 0

2x = - 6

x = - 6 : 2

x = - 3

8) 6x + 4 = 2x

6x - 2x = - 4

4x = - 4

x = - 4 : 4

x = - 1

9) y - 1 = 3y

y - 3y = 1

-2y = 1

y = 1 : (-2)

y = - 1/2

10) 7y - 14 = 0

7y = 14

y = 14 : 7

y = 2

11) 4z - 2 = z

4z - z = 2

3z = 2

z = 2/3

12) 7z = 3z - 6

7z - 3z = - 6

4z = - 6

z = - 6/4

z = - 3/2

13) 5x + 9 = - 3x + 4

5x + 3x = 4 - 9

8x = - 5

x = - 5/8

14) 6x = 1 - 9x

6x + 9x = 1

15x = 1

x = 1/15

15) - 3z + 6 = - 9z + 4

-3z+ 9z = 4 - 6

6z = - 2

z = - 2/6

z = - 1/3

16) 9x = - 8x + 7

9x + 8x = 7

17x = 7

x = 7/17

17) - 8x + 9 = - 9x

-8x + 9x = - 9

x = - 9

18) 6x - 8 = 7

6x = 7 + 8

x = 15/6

19) 5x - 3 = - 5

5x = - 5 + 3

x = - 2/5

20) - 3x - 7 = - 4x + 6

-3x + 4x = 6 + 7

x = 13
