2x-1/2[x-1/2(x-1)]=2/3(x-1)
2x-1/2[x-1/2x+1/2)]=2/3(x-1)
2x-1/2(1/2x+1/2)=2/3(x-1)
2x-1/4x-1/4=2/3(x-1)
两边同时乘以12，得
24x-3x-3=8(x-1)
21x-3=8x-8
21x-8x=-8+3
13x=-5
x=-5/13
2x-1/2(1/2x+1/2)=2/3(x-1)
2x-1/4x-1/4=2/3(x-1)
两边同时乘以12，得
24x-3x-3=8(x-1)
21x-3=8x-8
21x-8x=-8+3
13x=-5
x=-5/13
解得13/12x=-5/12，x=-5/13本回答被提问者采纳

解方程2x-1\/2[x-1\/2(x-1)]=1\/3(x-1)
2x-1\/2[x-1\/2(x-1)]=1\/3(x-1)则题目要求x不能为1 两边同时乘以6（x-1)化简得9（x-1\/2）^2=11\/4 3(x-1\/2)=+-√11\/2 x=1\/2+-√11\/6 根据我的步骤你自己来试试看，希望我的回答对你有帮助，谢谢！
二分之一[x-1\/2(x-1)]=2\/3(x-1)
两边*6 3[x-1\/2(x-1)]=2(x-1)3（x-x\/2+1\/2）=2x-2 3x\/2+3\/2=2x-2 4x\/2-3x\/2=2+3\/2 x\/2=2+3\/2 x=4+3 x=7
解方程 x-2[x-1\/2(x-1)]=2\/3(x+1)
解：X-2[X-1\/2X+1\/2]=2\/3X+2\/3 X-2X+X-1=2\/3X+2\/3 2X-2X-1=2\/3X+2\/3 -1=2\/3X+2\/3 -2\/3X=5\/3 X= - 5\/2 所以答案为X= - 5\/2 一元一次方程还是简单的，希望能帮到你！
