3x-1.5/0.2-0.2x-0.1/0.03=2.5
解方程:2- x+5/6=x- x-1/3,0.1-0.2x/0.03-1=0.7-x/0.4
(1)3x(x+0.2)=4x(x-1.1)
0.2/3x-1.5 8x=0.09/0.2x-0.1 4
(3x-1.5)/0.2+8x=(0.2x-0.1)/0.09+4 解方程
3(x-7)-5(4-x)=15 0.2分之0.1x+0.3+2.5=0.4x-1
(4x-1.5)/0.5-(5x-0.8)/0.2=(1.2-x)/0.1+3
(4x-1.5)/0.5-(5x-0.8)/0.2=(1.2-x)/0.1-3
解下列方程4x-1.5/0.5-5x-0.8/0.2=1.2-x/0.1-3
0.2分之3x-0.6=0.5分之2x-1.5-0.1分之x+4.2
5x+3=x-4,4y+11=22,11x+68-2x=100-9x,0.1x/0.2-(0.27x+0.18)/0.0
3x+0.5x=4.2 4x-2.16=1.2 x-0.2x=16 2x-4x[这个x是乘】2.5=3.6 3x+5x=
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
