1-(x-1)/3=(x+3)/2(2y+1)/4-1=y-(10y+1)/123x+(x+1)/2=3-(2x-1)/31-(x-1)/3=(x+3)/2(2y+1)/4-1=y-(10y+1)/1

1-(x-1)/3=(x+3)/2 (2y+1)/4-1=y-(10y+1)/12 3x+(x+1)/2=3-(2x-1)/3
1-(x-1)/3=(x+3)/2 (2y+1)/4-1=y-(10y+1)/12 3x+(x+1)/2=3-(2x-1)/3

1-(x-1)/3=(x+3)/2 (2y+1)/4-1=y-(10y+1)/12 3x+(x+1)/2=3-(2x-1)/3
1-(x-1)/3=(x+3)/2 两边同时乘以6得
6-2(x-1)=3(x+3)
6-2x+2=3x+9
3x+2x=6+2-9
5x=-1
x=-1/5
(2y+1)/4-1=y-(10y+1)/12 两边同时乘以12得
3(2y+1)-12=12y-(10y+1)
6y+3-12=12y-10y-1
6y-12y+10y=-1-3+12
