0.4x-2.1/0.5-0.5-0.2x/0.03=0.6
(0.4x-2.1)/0.5=(0.1+0.2x)/0.03-0.6
(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
x/0.5-0.4x-0.6/0.2=2(-x+3)
0.5x+3(0.3-0.2x)≥0.4x
x-30-0.2x=0.5x
0.02x-0.01/0.03-0.4x+0.2/0.5-3X+2/4=-3求x
2.1x-10.8=1.8, (x-0.4)÷0.5=2.4 ,0.9(x+0.4)=0.2.1x-10.8=1.8, (x-0.4)÷0.5=2.4 ,0.9(x+0.4)=0.45的方程,快速,必采纳哦!
一元一次方程计算题:0.4x+2.1/0.5=0.5-0.2x/0.03 +0.6
0.4x+2.1/0.5=0.5-0.2x/0.03+0.6的解方程
4x-1.5 5x-0.8 1.2-x --- - --- ＝ ---- 0.5 0.2 0.4x-1.5 5x-0.8 1.2-x--- - --- ＝ ----0.5 0.2 0.1
方程(初一水平)0.4x+2.1=0.5-0.2x+0.6(要用一元一次方程解)
解方程-0.4x+0.1=-0.5x+0.2
0.2分之x+0.4-0.5分之x-3=2?
3x/0.5-(7*0.2-x)/0.4=1急用!
x-1.5/0.5=1-(0.4x+1)/(0.2)
1+x/0.1-0.4x-0.5/0.2=1/2
