3/0.2x-0.1-0.05/(x+2)%=0.1x
解方程-0.4x+0.1=-0.5x+0.2
0.2分之0.1x+0.3+2.5=0.4x-1
0.2的平方x-0.1=0.4x公式法
0.2分之0.1x+3-0.4x-1=20
(0.4x-2.1)/0.5=(0.1+0.2x)/0.03-0.6
1+x/0.1-0.4x-0.5/0.2=1/2
(0.4x-2.1)/0.5=(0.1+0.2x)/0.03-6
(0.4x-2.1)/0.5=(0.1+0.2x)/0.03-0.6
0.4x+0.1-0.04分之0.01-0.2x=5.75
x/0.5-0.4x-0.6/0.2=2(-x+3)
