0.25x/x-2.5*0.6=0.50.25x/x-2.5*0.6=0.50.25x/x-2.5*0.6=0.50.25x/x-1.5=0.50.25x=0.5(x-1.5)0.25x=0.5x-0
0.25x/x-2.5*0.6=0.5
0.25x/x-2.5*0.6=0.5
0.25x/x-2.5*0.6=0.5
0.25x/x-1.5=0.5
0.25x=0.5(x-1.5)
0.25x=0.5x-0.75
0.25x=0.75
x=3
0.25x/x-2.5*0.6=0.5
x=1+0.5x+0.25x+0.125x+0.0625x求x的值
x+17=3(x+13),2x-11.2=0.6x,2.5x-2.17=21.9-5.8x,8(x-1.5)=x+0.6,2(0.5-x)+6=3x-2.53,用方程解
6x+15=87 8X-0.5x=15 x+0.6x=11.2
6(x-3)=2x 0.5(3+0.25x)=4 3.4-2(x+1.2)=0.6 16x-271=3(5-2x)
2.5x-1.8+0.5x=0.6 15.6-2(x-7.4)=12.4 0.86*2-7.1x=0.3 35-x=4(x+5) 解方程
求x的值 2.5:x=7.5:0.5 x= 2.4x+28.8=48 x= x-3分之2x=1.8 x= (1+5分之3)x=5分之2 x=x-3=3分之2 x= 15分之6:x=2:3 x= x:20分之7=4:x= x:0.6=4.5:2 x=急,
X+0.5X+0.25X=105怎么解?急
x/0.5-0.4x-0.6/0.2=2(-x+3)
(0.2x+0.5)/0.04+(x-3)/0.6=12x
0.5(X+8)=0.6x求x
2.5X-0.5X=18.5 x/3.14=8
15=2.5X一0.5X X=?
4-x=2(-0.5x²+2.5x-2)
2.5x-0.6=1.3x
解方程:x-0.5x=0.25
0.25x=0.5(13-x)
0.25X+3.2=0.5X-5.2
