Sagot:
# x = -8 / 3 #
# y = 17/6 #
Paliwanag:
# 5x + 4y = -2 #
# x-4y = -14 #
Sa pamamagitan ng pagdaragdag ng unang equation sa ikalawang equation na nakukuha namin
# 5x + 4y + x-4y = -2-14 #
# x-4y = -14 #
# 6x = -16 #
# x-4y = -14 #
# x = -16 / 6 #
# x-4y = -14 #
# x = -8 / 3 #
# -8 / 3-4y = -14 #
# x = -8 / 3 #
# 4y = -8 / 3 + 42/3 #
# x = -8 / 3 #
# 4y = 34/3 #
# x = -8 / 3 #
# y = 34/12 #
# x = -8 / 3 #
# y = 17/6 #
