61 + [( - 5x + ( - 2x + 3)] = 15 - (4x + 3)?

61 + [( - 5x + ( - 2x + 3)] = 15 - (4x + 3).

En resumen

61 + [( - 5x + ( - 2x + 3))] = 15 - (4x + 3) 61 + [ - 5x - 2x + 3] = 15 - 4x - 3 61 + [ - 7x + 3] = 12 - 4x 61 - 7x + 3 = 12 - 4x - 7x + 64 = 12 - 4x - 7x + 4x = 12 - 64 - 3x = - 52 X = - 52 / - 3 X = 52 / 3 Solución final : X = 52 / 3 Saludos.

61 + [( - 5x + ( - 2x + 3))] = 15 - (4x + 3)

61 + [ - 5x - 2x + 3] = 15 - 4x - 3

61 + [ - 7x + 3] = 12 - 4x

61 - 7x + 3 = 12 - 4x - 7x + 64 = 12 - 4x - 7x + 4x = 12 - 64 - 3x = - 52

X = - 52 / - 3

X = 52 / 3

Solución final :

X = 52 / 3

Saludos.
