(3 / 5)(x + 1) + (3 / 5)x = (x - 1) - 10?
(3 / 5)(x + 1) + (3 / 5)x = (x - 1) - 10.
(3 / 5)(x + 1) + (3 / 5)x = (x - 1) - 10.
En resumen
3 / 5 x + 3 / 5 + 3 / 5 x = x - 1 - 1'0 3 / 5 x + 3 / 5 x - x = - 1 - 10 - 3 / 5 3 / 5 x + 3 / 5 x + 5 / 5 x = - 5 / 5 - 50 / 5 - 3 / 5 16 / 5 x = - 58 / 5 x = ( - 58 / 5) / (16 / 5) x = - 290 / 80 = 145 / 40 = 29 / 8 = 3 5 / 8.
3 / 5 x + 3 / 5 + 3 / 5 x = x - 1 - 1'0
3 / 5 x + 3 / 5 x - x = - 1 - 10 - 3 / 5
3 / 5 x + 3 / 5 x + 5 / 5 x = - 5 / 5 - 50 / 5 - 3 / 5
16 / 5 x = - 58 / 5
x = ( - 58 / 5) / (16 / 5)
x = - 290 / 80 = 145 / 40 = 29 / 8 = 3 5 / 8.
