Answer 1

Respuesta:

1) x = -8

2) x = 5

3) x = 2

4) x = 10

5) x = 1

Explicación paso a paso:

1) 3x + 2 = 2x - 6

3x - 2x = -6 -2

x = -8

2) 7x + 13 = 4x + 28

7x - 4x = 28 - 13

3x = 15

x = 15/3

x = 5

3) 3x + 6 + 4x - 2 + 5x - 4 + 6x = 36

(3x + 4x + 5x + 6x) = 36 + (6 -2 -4)

18x = 36 + 0

x = 36/18

x = 2

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

5x - 3x = 8 -x + 8 + 14

2x = 30 -x

2x + x = 30

3x = 30

x = 30/3

x = 10

5) x + 3(x - 2) = 2x – 4

x + 3x - 6 = 2x - 4

4x - 6 = 2x - 4

4x - 2x = -4 + 6

2x = 2

x = 2/2

x = 1
