En resumen
(4x - 6 + 5x) + (9 - 5x + 3 - 2x) = 7x - (1 - 6x) (9x - 6) + (9 + 3 - 7x) = 7x - (1 - 6x) 9x - 6 + 9 + 3 - 7x = 7x - 6x - 1 9x - 7x - 1x = ( - 1) + 6 - 9 - 3 1x = - 7 x = - 7 : 1 x = - 7.
(4x - 6 + 5x) + (9 - 5x + 3 - 2x) = 7x - (1 - 6x)
(9x - 6) + (9 + 3 - 7x) = 7x - (1 - 6x)
9x - 6 + 9 + 3 - 7x = 7x - 6x - 1
9x - 7x - 1x = ( - 1) + 6 - 9 - 3
1x = - 7 x = - 7 : 1 x = - 7.
(4x - 6 + 5x) + (9 - 5x + 3 - 2x) = 7x - (1 - 6x) (9x - 6) + (9 + 3 - 7x) = 7x - (1 - 6x) 9x - 6 + 9 + 3 - 7x = 7x - 6x - 1 9x - 7x - 1x = ( - 1) + 6 - 9 - 3 1x = - 7 x = - 7 : 1 x = - 7.
