0.25x-2.6=5.65 0.125*(x+3)=1 2.5*4+2.5x=18
0.25x-2.6=5.65 0.125*(x+3)=1 2.5*4+2.5x=18
0.25x-2.6=5.65 0.125*(x+3)=1 2.5*4+2.5x=18
4-2.5x=1 2.5x=4-1 2.5x=3 x=1.2 18-2.5x=6 2.5x=12 x=4.8 3.6x-x=3.25 2.6x=3.25 x=1.25 2(x-3)=5.8 x-3=2.9 x

12.02 5 3.2
0.25x-2.6=5.65 0.125*(x+3)=1 2.5*4+2.5x=18
x=1+0.5x+0.25x+0.125x+0.0625x求x的值
0.25x=0.125(120-x)+15
(0.5x+1)+(0.25x+0.5)+(0.125x+2.25)=x怎么解,
12.4x-7.8x=23 5(x-1.9)=10.5 3x-2.6x=0.25乘于2
2.6x-x-0.1x=0.75
（x-4)-(x+4)=0.25x
66=X+0.25X求X
0.25x+3.6=x解x
(0.25-x)/0.125=0.625
x:8=0.125:0.25
x-0.25=0.25x
360-x=2.6x
x-0.25x+1=10.4x+0.25x-1
x-0.25x=0.
X-0.25x=0.
x-0.25x=48
x-35%x=0.25
