神马品牌网林方文到底爱不爱程韵:简单的初中数学题
来源：百度文库 编辑：神马品牌网 时间：2024/05/03 03:06:42
12(x-3)-6(x+3)=0
(y+2)/3-(4y-1)/3 =2-(2y+5)/6
帮忙解上面三道题,请把过程写出来
6(2x-2)-x=92
12x-12-x=92
11x=104
x=104/11
12(x-3)-6(x+3)=0
12x-36-6x-18=0
6x=54
x=9
(y+2)/3-(4y-1)/3 =2-(2y+5)/6
y/3+2/3-(4/3)y+1/3=2-y/3 -5/6
-(2/3)y=1/6
y=-1/4

6(2x-2)-x=92
12x-12-x=92
11x=104
x=104/11
12(x-3)-6(x+3)=0
12x-36-6x+18=0
6x=18
x=3
(y+2)/3-(4y-1)/3 =2-(2y+5)/6
2(y+2)-2(4y-1)=12-(2y+5)
2y+4-8y+2=12-2y-5
4y=-1
y=-1/4
12x-12-x=92 x=104/11
12x-36-6x-18=0 x=9
(-3y+3)/3=2-(2y+5)/6 (-4y+5)=6 y=-1/4
1、12X-12－X=92
11x＝104 X＝9.45 （注：此题题目中应该是＋X,这样，13X＝104 X＝8）
2、12X-36-6X-18=0
6X=54 X=9
3、2(Y+2)-2(4Y-1)=2*6-(2Y+5)
2Y+4-8Y+2=12-2Y-5
6-6Y=7-2Y
4Y=-1 Y=-1/4
6(2x-2)-x=92
12x-12-x=92
11x=104
x=104/11
12(x-3)-6(x+3)=0
12x-36-6x-18=0
6x=54
x=9
(y+2)/3-(4y-1)/3 =2-(2y+5)/6
y/3+2/3-(4/3)y+1/3=2-y/3 -5/6
-(2/3)y=1/6
y=1/4
懂了吗
