Por favor ayuden con este ejercicio:
2 (3x + 2) = 4 [2x - 5 (x - 2)] =
6x + 4 = 4 [2x - 5x + 10] =
6x + 4 = 4 [- 3x + 10] =
6x + 4 = - 12x + 40 =
6x + 12x = 40 - 4
18x = 36
x = 36/18
x = 2
Rpt. El valor de x es 2.
COMPROBAMOS LA SOLUCIÓN.
2 (3x + 2) = 4 [2x - 5 (x - 2)] =
2 (3 * 2 + 2) = 4 [2 * 2 - 5 (2 - 2)] =
2 (6 + 2) = 4 [4 - 5 (0)] =
2 (8) = 4 [4 - 0] =
16 = 4 [4] =
16 = 16
LISTO!
2 (3x + 2) = 4 [2x - 5 (x - 2)] =
6x + 4 = 4 [2x - 5x + 10] =
6x + 4 = 4 [- 3x + 10] =
6x + 4 = - 12x + 40 =
6x + 12x = 40 - 4
18x = 36
x = 36/18
x = 2
