x-0.5x=3.2 解方程
X/3.2=0.5
3.2/X=0.5
1、0.5x+30=15.5x 2、3.2x-12.6=1.2x
0.5x(x+4)-0.4(x+4)=3.2 x是多少
3.2+x=4.6 x-2.08=5.76 1.2x=0.84 3x+0.5x=4.2 4x-2.16=1.2 x-0.
4X减0.5X等于1.75 X除0.63=12 5X加X=20 5X减3X=3.2
4X+0.5X=13.5X
x+180%x=3.2
x+0.5x=30
求未知数X .3.2/3X=0.5
解方程;x/0.5-10+2=0 4(0.9-x)=3.2x 6.4-2(x+1.2)=0.4
