Two piles of yellow sand are 5.7 tons in total. 34 tons are used in the first pile and 35 tons in the second pile. The remaining two piles are 15 tons less than the first pile. How many tons are there in the first pile?

Set the first pile as unit "1". The first pile uses 34, and there are still 14 left. The second pile uses 35, and there are still 25 left. Together, the second pile is the first pile: 1-15-14 = 1120, that is, 25 of the second pile is equivalent to 11201120 △ 25 = 118 of the first pile, that is, the second pile is equivalent to 118 of the first pile, 5.7 △ 1 + 118, = 5

There are two piles of coal, a and B, with a total of 19 tons. If 5 / 2 of it is transported from the first pile and 3 tons is transported from the second pile, then the two piles of coal are equal and the first pile of coal is equal

1-2/5=3/5
The second pile used to be 3 tons more than 3 / 5 of the first pile
The first batch: (19-3) △ 1 + 3 / 5) = 10 tons
Stack 2: 19-10 = 9 tons

There are a total of 19 tons of coal in two piles a and B. two fifths of the coal are transported from the first pile and three tons are transported from the second pile. At this time, the two piles are the same weight. How much is the weight of the first pile

If there is x in pile a, then B is 19-x
3/5*X=19-X-3
X=10
So there are 10 tons in pile a
