0.9/(X+0.4)=0.450.9/(X+0.4)=0.450.9/(X+0.4)=0.45(X+0.4)=0.9/0.45x+0.4=2x=1.6x=.1你好0.9/(X+0.4)=0.450.
0.9/(X+0.4)=0.45
0.9/(X+0.4)=0.45
0.9/(X+0.4)=0.45
(X+0.4)=0.9/0.45
x+0.4=2
x=1.6
x=.1
你好
0.9/(X+0.4)=0.45
0.9=0.45(x+0.4)
0.9=0.45x+0.45×0.4
0.9=0.45x+0.18
0.45x=0.9-0.18
x≈1.38
希望帮到你
0.9/(X+0.4)=0.45
(x+x)+(x-x)+(x/x)=11.2
(18+x)-0.4x=19.2 求x
7.72-x=1.8(x+0.4)
0.8X(x-0.4)=8
x^2=(0.4X)(0.

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!
12(0.4x+0.9)-2(0.03+0.05x)=300(x-5) x=?
(0.4x+0.9)/0.5-(0.03+0.02x)/0.03=(x-5)/2 x等于多少?
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
0.9(17-X-2X)+0.7(2X)+0.5X=12.9怎么解?
6x-2(340-3x)=220 18+0.4x=22.2-x
6x-2(340-3x)=220 18+0.4x=22.2-x
0.03+0.02x/0.03=0.4x+0.9/0.5-x-5/2这个“/”是分数线的意思!0.03+0.02x/0.03=0.4x+(0.9/0.5)-(x-5/2)
解方程:{(0.4x+0.9)/0.5}-{(0.03+0.02x)/0.03}=(x-5)/2
0.5分之(0.4x+0.9)-0.03分之(0.03+0.02x)=2分之(x-5)
解方程4(x-0.9)=2.2x 解方程0.4=6.4-2(x+1.2)
