4x + 5 - 6x + 10x = 43 - 2x + 2 - 5x
14x - 6x + 5 = 45 - 7x
8x + 5 = 45 - 7x
8x + 7x = 45 - 5
15x = 40
x = 40/15 Simplificando
x = 8/3
Respuesta.
x = 8/3
4x + 10x - 6x + 5 = - 2x - 5x + 43 + 2
14x - 6x + 5 = - 7x + 45
8x + 5 = - 7x + 45
8x + 7x = 45 - 5
15x = 40
x = 40/15
x = 8/3
Solución :
x = 8/3
