0.2(0.2)/0.01+1.2x=0.12+20x解方程!
0.2(0.2)/0.01+1.2x=0.12+20x解方程!
0.2(0.2)/0.01+1.2x=0.12+20x解方程!
0.04/0.01=0.12+18.8x
18.8x=4-0.12
18.8x=3.88
x=970/47
0.2(0.2)什么意思，平方还是什么
0.2(0.2-x)/0.01+1.2x=0.12+20x
0.2(0.2-x)÷0.01+1.2x=0.12+20x
0.01分之0.2（0.2 -x)+1.2x=0.12+20x
[0.2(0.2-x)]÷0.01+1.2x=0.12+20x
一元一次方程 2x+0.2=1.2x-0.6-2.2x
0.8x+3=1.2x+0.2怎么求x
0.2x-1.2=0.6+x
x-0.2(x+8)=0
0.01分之0.2(0.2-x) +1.2x=0.12+20x0.01分之0.2(0.2-x)是一项 +1.2x是一项 0.12+20x是一项
1.2x-5=x+5 1.2x-x=5+5 0.2x=10 x=50
x-30-0.2x=0.5x
x-0.2x=80 求x
0.02x-0.01/0.03-0.4x+0.2/0.5-3X+2/4=-3求x
4x一5/0.5—5x-0.8/0.2=1.2-x/0.1 x=
(X-8)/X=0.2(X-8)/X=0.2
X-X×0.2=1.18
x-0.2.x=180
x-0.2x=36
