Ответ:

x=-8/5

Пошаговое объяснение:

$2x+(\frac{1}{3}x -\frac{11}{9} )*(-\frac{9}{4})=\frac{3}{4} \\2x-\frac{3}{4}x +\frac{11}{4} =\frac{3}{4} \\\frac{5}{4} x+\frac{11}{4}=\frac{3}{4} \\5x+11=3\\5x=3-11\\5x=-8\\x=-\frac{8}{5} =-1,6$

Since an old man and his son wanted to sell their donkey at the town market far away from their home, they had to take the animal to the town. They hardly (leave) their home when a neighbour called to them. “Why you (walk) when you have a donkey?” he asked. The old man (put) his son on the donkey while he continued to lead. They (be) about halfway to town when three women standing by the side of the road scolded the boy. “You should be ashamed of yourself, riding when your father (have) to walk,” one of the women said. “You (be) right, I guess,” the old man said. “Let me get on behind you, son.” They almost (reach) the town when a group of villagers began laughing at them. “You should be carrying that poor beast, instead of making him carry both of you.” So the old man and his son (get down) and (tie) the animal to a pole so that they (can) carry it. But as they (cross) the bridge near the marketplace, the donkey (kick) loose from the pole and (fall) into the stream and (drown). “Our donkey (be) dead now, and it should teach us,” the old man said sadly to his son. “If we hadn’t tried to please everybody our donkey would have been alive,” he added. “Whenever we try to please everyone, we (lose).”
