6.8 (x-3.6)= 0.8x
6.8 (x-3.6)= 0.8x
6.8 (x-3.6)= 0.8x
6.8 (x-3.6)= 0.8x
6.8 x-6.8×3.6=0.8x
6x=6.8×3.6
x=4.08
6.8x-6.8*3.6=0.8x
6x=6.8*3.6
x=6.8*0.6
x=4.08
太简单了楼下已解
等于4.08
6.8 (x-3.6)= 0.8x
6.8x-24.48=0.8x
6x=24.48
x=4.08
6.8 (x-3.6)= 0.8x
(x+x)+(x-x)+(x/x)=11.2
X+0.8X=?
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
6.8x-0.8+3.5=8.6x
(1十40%)X乘0.8-X=3.6
8(X一3.6)=0.8x
3.6x-x=3.252(x-3)=5.8
(x+x-15)×3.6=486
1.x-0.7x=2.342.x-0.8x=123.4(3x-x)=64
18.6-x=0.8(12+x)
0.8X(x-0.4)=8
X-(0.8-X)=16
0.8X-(X-7)=3
解方程:5-(x-6.8)=12 7x+0.8x=9.36
四道方程:2x+6=5x 6x-28=2x 8(x-3.6)=0.8x 15x-110+7x=110
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
13x-6.8x+x=46.
