解两道方程题；1/2[x-1/2(x+1)]=2/3 (x-1) 1/3(x-1)+1/4(x-1)-1/2(x-1)=1
解两道方程题；1/2[x-1/2(x+1)]=2/3 (x-1) 1/3(x-1)+1/4(x-1)-1/2(x-1)=1
解两道方程题；1/2[x-1/2(x+1)]=2/3 (x-1) 1/3(x-1)+1/4(x-1)-1/2(x-1)=1
1/2[x-1/2(x+1)]=2/3 (x-1)
1/2[x-1/2x-1/2)]=2/3 (x-1)
1/4[x-1]=2/3 (x-1)
1/4[x-1]-2/3 (x-1)=0
(1/4-2/3)[x-1]=0
x-1=0
x=1
1/3(x-1)+1/4(x-1)-1/2(x-1)=1
(1/3+1/4-1/2)(x-1)=1
1/12 (x-1)=1
x-1=12
x=13
