2x - 1 = x - 5 o 2x - 1 = - (x - 5)?
2x - 1 = x - 5 o 2x - 1 = - (x - 5).
En resumen
2x - 1 = x - 5 2x - x = - 5 + 1 x = - 4 2x - 1 = - (x - 5) 2x - 1 = - x + 5 2x + x = 5 + 1 3x = 6 x = 6 / 3 x = 2.
Mejor respuesta
2x - 1 = x - 5
2x - x = - 5 + 1
x = - 4
2x - 1 = - (x - 5)
2x - 1 = - x + 5
2x + x = 5 + 1
3x = 6
x = 6 / 3
x = 2.
