2x-二分之一[x-二分之一(x-1)]=三分之一(x-1)
2x-[x-(x-1)\/2]\/2=(x-1)\/3 2x-(x-x\/2+1\/2)\/2=(x-1)\/3 12x-3(x\/2+1\/2)=2(x-1)12x-3x\/2-3\/2=2x-2 12x-3x\/2-2x=3\/2-2 17x\/2=-1\/2 x=-1\/17
2x减去二分之一{X-二分之一(x-1)}=三分之二(x-1)
2x-1\/2[x-1\/2(x-1)]=2\/3(x-1)12x-3[x-1\/2x+1\/2]=4(x-1)12x-3x\/2-3\/2=4x-4 24x-3x-3=8x-8 24x-3x-8x=-8+3 13x=-5 x=-5\/13
2x减2分之1乘【x减2分之1乘(x减1)】等于3分之2乘(x减1)(解方程)

...3 (x减1)等于1 1又2分之1x加3分之1x等于6分之一
X=(1\/2+1\/2)\/2=1\/2 X=1\/3+1=4\/3 X=1\/6*2\/3=1\/9
x-2\/1[x-2\/1(x-1)]=3\/2(x-1) 2\/1{2\/1[2\/1(x-1)+1]+x}+1=3
x-2\/1[x-2\/1(x-1)]=3\/2(x-1)x-1\/2[x-1\/2x+1\/2]=2\/3x-2\/3 x-1\/2[1\/2x+1\/2]=2\/3x-2\/3 x-1\/4x-1\/4=2\/3x-2\/3 3\/4x-2\/3x=1\/4-2\/3 1\/12x=-5\/12 x=-5 2\/1{2\/1[2\/1(x-1)+1]+x}+1=3 1\/2{1\/2[1\/2x-1\/2+1]+x}=2 1\/2[1\/2x+1\/...
2分之1【x-2分之1(x-1)】=3分之2
详细步骤写在纸上了
x-二分之一[x-二分之一(x-1)]=三分之二(x-1)
x-1\/2[x-1\/2(x-1)] = 2\/3(x-1)x-1\/2x-1\/4(x-1) = 2\/3x-2\/3 1\/2x-1\/4x+1\/4 = 2\/3x-2\/3 1\/4x+1\/4 = 2\/3x-2\/3 2\/3x-1\/4x = 2\/3-1\/4 (8-3)x=8+3 x=11\/5
x-2[x-2分之1(x-1)]=3分之2(x+1)过程
x-2[x-2分之1(x-1)]=3分之2(x+1)x-2(x-1\/2x+1\/2)=2\/3x+2\/3 x-2(1\/2x+1\/2)=2\/3x+2\/3 x-x-1=2\/3x+2\/3 2\/3x=-5\/3 x=-5\/3*3\/2 x=-5\/2 希望我的回答能够帮到你,顺祝愉快!
