Answer 2

Respuesta:

x = 5; x = 1; x = 14,07; x = 0,5; x = - 3

Explicación paso a paso:

3x - 2 = x + 8.

3x - x = 8 + 2

2x = 10

x = 5

x + 2x + 3x = 1 + 2 + 3

6x = 6

x = 6 : 6

x = 1

4x + 3,72 = 60

4x = 60 - 3,72

4x = 56,28

x = 56,28 : 4

x = 14,07

2x - 5 + 6x + 3 = 3x + 2 - x - 1

2x + 6x - 3x +x = 2 - 1 - 3 + 5

6x = 3

x = 3 : 6

x = 1 : 2

x = 0,5

2x - 1 = 5x + 8

2x - 5x = 8 + 1

-3x = 9

x = - (9 : 3)

x = - 3
