'simple (ha! not for me - mathematically challenged!) equations'. Can anyone show simple working out for following:-
-x + 3 = 6
-x - 3 = 7
9x - 6 = 8
6x = 28
a_
4 = 7
3 (2x + 5) = 75
In hope.......

Takes Indirubin content from Dyers Woad Leaf as the index，compare the best extraction process between decoction and lifting reduction for ethanol，and take the L9 orthogonal experiment，do a research for the different level of factor that effect the Dyers Woad Leaf. The result shows that：The best extraction process is the lifting reduction for ethanol. The best extraction craft for Indirubin from Dyers Woad Leaf is crude drug reflux three times in ten time of 70% alcohol solution and two hours each-time.
