4（2x-1）=3(x+2)-12
8x-4=3x+6-12
8x-3x=6+4-12
5x=-2
x=-0.4
去分母得4(2x-1)=3(x+2)-12
去括号得 8x-4=3x-6
移项得 5x=-2
合并得 x=-2/5
x=1/2+1/3-1=-1/6追问
详细一下
追答2X-1/3=X+2/4-1；
移项得：2x-x=1/3+2/4-1;
x=2/6+3/6-6/6;
x=-1/6
4(2x-1)=3(x+2)-12
8x-4=3x+6-12
8x-3x=-6+4
5x=-2
x=-2/5
X=-1/6
2X-1\/3=X+2\/4-1怎么求
我对你们无语(2x-1)\/3=(x+2)\/4-1 两边乘12 4（2x-1）=3(x+2)-12 8x-4=3x+6-12 8x-3x=6+4-12 5x=-2 x=-0.4
2x-1\/3=x+2\/4-1 怎么解?一元一次方程! 急、、、
(2x-1)\/3=(x+2)\/4-1 (2x-1)\/3=(x-2)\/48x-4=3x-65x=2x=2\/5
2x-1\/3=x+2\/4-1
2x一1\/3=x+2\/4-1 解:2ⅹ一1\/3=ⅹ-1\/2 2ⅹ一ⅹ=-1\/2+1\/3 ⅹ=-3\/6+2\/6 ⅹ=-1\/6
问方程2x-1\/3=x+2\/4-1怎么解
4(2x-1)=3(x+2)-12 8x-4=3x+6-12 8x-3x=6-12+4 5x=-2 x=-2\/5
2x-1\/3=x+2\/4-1
方程两边同乘12 4(2x-1)=3(x+2)-12 8x-4=3x-6 5x=-2 x=-2\/5 望采纳
2x-1\/3=x+2\/4 -1
2x-1\/3=x+2\/4-1 解： 2x-x=1\/2-1+1\/3 x=-1\/6 O(∩_∩)O~
2x-1\/3=x+2\/4-1用初一的知识解,要有步骤
2x-1\/3=x+2\/4-1 两边同乘以12 得 24x-4=12x+6-12 12x=-2 x=-1\/6
2X-1\/3=x+2\/4-1要过程
2X-1\/3=x+2\/4-1 2x-x=1\/3+1\/2-1 x=-1\/6
2X-1\/3=(X+2\/4)-1
2x-1\/3=x-1\/2 2x-x=1\/3-1\/2 x=-1\/6
2x-1\/3=x+2\/4-1 x-减x-2\/5=2x-5\/3减3
2x-1\/3=x+2\/4-1 两边乘12 4(2x-1)=3(x+2)-12 8x-4=3x+6-12 5x=-10 x=-2 x-减x-2\/5=2x-5\/3减3 两边乘15 15x-3(x-2)=5(2x-5)-45 15x-3x+6=10x-25+45 2x=14 x=7
