En resumen

6× - 1 + × = 4 - 5× + 3 5x - 1 = 7 - 5x 5x + 5x = 7 + 1 10x = 8 x = 8 / 10 x = 4 / 5 x + 2× + 3× - 5 = 4× - 9 6x - 5 = 4x - 9 6x - 4x = - 9 + 5 2x = - 4 x = - 4 / 2 x = - 2.

6× - 1 + × = 4 - 5× + 3

5x - 1 = 7 - 5x

5x + 5x = 7 + 1

10x = 8

x = 8 / 10

x = 4 / 5

x + 2× + 3× - 5 = 4× - 9

6x - 5 = 4x - 9

6x - 4x = - 9 + 5

2x = - 4

x = - 4 / 2

x = - 2.
