(x+3.2)/250=(x-3.2)/90怎么解(x+3.2)/250=(x-3.2)/90怎么解(x+3.2)/250=(x-3.2)/90怎么解(x+3.2)/250=(x-3.2)/90(x+
(x+3.2)/250=(x-3.2)/90怎么解
(x+3.2)/250=(x-3.2)/90怎么解
(x+3.2)/250=(x-3.2)/90怎么解
(x+3.2)/250=(x-3.2)/90
(x+3.2)/(x-3.2)=25/9
2x/(x-3.2)=34/9
9x=17x-54.4
8x=54.4
x=6.8
经检验,x=6.8是原方程的根
x+180%x=3.2
x-0.36x=3.2
x+3.2x=4.8 16+7x=45 5.2x-x=32.4
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x =100
(x+3.2)/250=(x-3.2)/90怎么解
x-2/5x=3.2 x=
解方程:3.2x=170%x+22.5 x=( )
已知|x-3.2|=|7.1-x|,则x=
0.5x(x+4)-0.4(x+4)=3.2
0.4x+3.2=2.5x+0.05 X是多少
求(x-2.6)+(x-3.2)=x+2.8的解
15x+(3.2x+2)×3=6x+2
1.6X(X-5)=3.2 X是多少?
1.6X(X-5)=3.2 X是几?
7.2x-3.2x-7.8=12.
x-0.5x=3.2 解方程
x+55=3.2x 解方程
3.2x+1.8x=7.8
