(141373.1016+5X)/(29852+X)=4.8 X等于多少?要公式.195.561061
(141373.1016+5X)/(29852+X)=4.8
(141373.1016+5X)=4.8*(29852+X)
141373.1016+5X=4.8*29852+4.8X
141373.1016+5X=143289.6+4.8X
5X-4.8X=143289.6-141373.1016
0.2X=1916.4984
X=9582.492
5x+(29-x)*3=29
求y=2x+5/x-29（x
9x+13=29-5x
（(29+x)/(5+x)=19/7

4x-3(x-5)=2x+(x-1) (3x+29)除以8=4x 7(x+10)=5(4x-10) 5分之2（x-15）+x=69
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
