Resolver :  (3x + 2) – ( - x – 1) = (2x + 4) + (x + 3)  4x + 9 = 2x – 3 + x  3( x + 2) – 5 ( 4 – 7x) = 8.

En resumen

(3x + 2) – ( - x – 1) = (2x + 4) + (x + 3) 3x + 2 + x + 1 = 2x + 4 + x + 3 3x + x - 2x - x = 4 + 3 - 2 - 1 x = 4 4x + 9 = 2x – 3 + x 4x - 2x - x = - 3 - 9 x = - 12 3( x + 2) – 5 ( 4 – 7x) = 8 3 x + 6 - 20 + 35x = 8 3x + 35x = 8 - 6 + 20 38x = 22 x = 22 / 38 x = 11 / 19.

(3x + 2) – ( - x – 1) = (2x + 4) + (x + 3)

3x + 2 + x + 1 = 2x + 4 + x + 3

3x + x - 2x - x = 4 + 3 - 2 - 1 x = 4

4x + 9 = 2x – 3 + x

4x - 2x - x = - 3 - 9 x = - 12

3( x + 2) – 5 ( 4 – 7x) = 8

3 x + 6 - 20 + 35x = 8

3x + 35x = 8 - 6 + 20 38x = 22 x = 22 / 38 x = 11 / 19.
