Răspuns:
# x = -21 / 8 #
Explicaţie:
# x -6/4 - 2x + 1/2 - 3 = x / 3 - 1/2 #
# x -3/2 - 2x + 1/2 - 3 = x / 3 - 1/2 #
# (x - 2x) + (- 3/2 + 1/2 - 3) = x / 3 - 1/2 #
# (- x) + (- 1 - 3) = x / 3 - 1/2 #
# (- x) + (- 4) = x / 3 - 1/2 #
# -x - 4 + (-x / 3) = x / 3 - 1/2 + (-x / 3) #
# - (1 1/3) x - 4 = - 1/2 #
# - (1 1/3) x - 4 + (4) = - 1/2 + (4) #
# - (1 1/3) x = 3 1/2 #
# -4 / 3x = 7/2 #
# -4 / 3 * (3/4) x = 7/2 * (3/4) #
# - x = 21/8 #
# - x * (- 1) = 21/8 * (- 1) #
# x = -21 / 8 #
Doamne, nu mi se pare deloc. Tu espero que esto ayudase.
