2) = -3
3) 3x - 3 = 9
4) 5x + 1 = 11
5)+5 = 12
6-1 = 10
7) 4x + 3 = 19
8) x - 2 = 6
9 -2 = 10
10

Answer 1

Respuesta:

1. = 2

3. = 4

4. = 2

6. = 2

7. = 4

8. = 9

Explicación paso a paso:

1.

3x = 9 - 3

3x = 6

x = 6/3

x = 2

3.

3x - 3 = 9

3x = 9 + 3

3x = 12

x = 12 / 3

x = 4

4.

5x + 1 = 11

5x = 11 -1

5x = 10

x = 10 /5

x= 2

6.

6 - 1 = 10

5 = 10

2

7.

4x + 3 = 19

4x = 19 - 3

4x = 16

x = 16/4

x = 4

8.

x - 2 = 6

1x = 6

x = 6

9.

9 - 2 = 10

7 = 10

10/ 7
