1.x/0.3+8/3-1.4-3x/0.2=14 2.0.1x+4/0.5+0.1x+2/0.2=10
解方程 (0.1x+2)/0.3-(x-1)/0.5=1.2 2y/0.3-(1.4-3y)/0.2=-8/3
(0.2/x+4)-(0.5/x-3)=1.4去括号和去分母
x+4 x-3___ - ___ = 1.4 请问这道题怎么算?一定要对!0.2 0.5
x=0.5*(1.4-2x)^2求解
0.2:0.5 = X:
4-1.4(2X-3)=0.5解方程
2-0.2(y-2)=x+0.1/0.5y-0.2/0.4=0.2-x/0.2
0.2*2+0.5x ---------------- =2 0.15*2+0.2x0.2*2+0.5x---------------- =2 0.15*2+0.2x
X+3/0.2-2X-1/0.5=0.5
