解：0.7x/3=8.19

3x 0.7x=2.3中的x怎么解 解：0.7x/3=8.19 解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6) 0.7x/3=8.19! 解方程63—3X=2X和X-0.5X+0.7X=0.12 解方程:2- x+5/6=x- x-1/3,0.1-0.2x/0.03-1=0.7-x/0.4 解方程x²-x=x³-3x. 解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7) 解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3) 解方程：（x-8）/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3) 解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8) 解分式方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8
