2[3x - (4x - 6)] = 5(x - 6)4{2 - [3(c + 1) - 2(c + 1]} = - 2c?

2[3x - (4x - 6)] = 5(x - 6) 4{2 - [3(c + 1) - 2(c + 1]} = - 2c.

En resumen

1. - 2[3x - 4x + 6] = 5x - 30 6x - 8x + 12 = 5x - 30 6x - 8x - 5x = - 30 - 12 - 7x = - 42 ( - 1) Respuesta : x = 6 7x = 42 x = 42 / 7 x = 6 2.

1. - 2[3x - 4x + 6] = 5x - 30 6x - 8x + 12 = 5x - 30 6x - 8x - 5x = - 30 - 12 - 7x = - 42 ( - 1) Respuesta : x = 6 7x = 42 x = 42 / 7 x = 6

2.

- 4{2 - [3c + 3 - 2c - 2]} = - 2c 4{2 - 3c - 3 + 2c + 2} = - 2c 4{ - c + 1} = - 2c - 4c + 4 = - 2c Respuesta : c = 2 - 4c + 2c = - 4 - 2c = - 4 ( - 1) 2c = 4 c = 4 / 2 c = 2.
