(0.4x-2.1)/0.5=(0.1+0.2x)/0.03-0.6
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-0.4x+0.1=-0.5x+0.2
14.5-2(x+3)÷5=0.5x÷0.1-(0.4x-2.8)÷0.6
0.1x-3\0.2+0.3x+0.5\0.6=x-1\3
0.2分之3x-0.6=0.5分之2x-1.5-0.1分之x+4.2
0.2x+0.4x=12 x=?20x+x=420 x=?
0.4x+2.1-0.03分之0.5-0.2x=5分之3
0.04分之0.1X-0.3-X=0.4乘以(0.5X-3)求X
2- 6分之x+5=x- 3分之x-1 ,0.03分之0.1-0.2x-1=0.4分之0.7-x 怎么解方程!急
2x-0.8×2.6=3.08-2x 2.4×0.2x=0.5x-2.4 5(0.2x-2.5)=2.1x
第一题0.2分之x-1减去0.5分之x+1=0.2第二题0.1x-0.2减去1=0.1分之0.01x+0.03
0.2分之0.1x+0.3+2.5=0.4x-1
