A batch of coal for heating in winter was transported from schools in the urban area. In December, 2 / 3 of the total coal was used, less than 2 tons. In January, the remaining 40% of the total coal was used, more than 3 tons. At this time, there were 6 tons left, How many tons of this coal?

Assuming that the total amount of coal is x tons, the coal consumption in December is 2x / 3-2 tons, and that in January is 0.4 [x - (2x / 3-2)] + 3 tons,
x-(2x/3-2)-{0.4[x-(2x/3-2)]+3}=6
The solution is x = 39
That is 39 tons of coal in total
