X-（3/2+4/1)=12/11
问题描述：
X-（3/2+4/1)=12/11
答
除不开x=81/44
答
X-(12/8+12/3)=12/11
X-12/11=12/11
X-12/11+12/11=12/11+12/11
X=12/22
答
x=81/44
答
x=12/11+(3/2+4/1)=12/11+11/2=145/22
答
X-（3/2+4/1)=12/11
x-1.5=1.090909090
x=1.090909090-1.5
x=0.40909091
答
x-3/2-4/1=12/11
x=12/11+3/2+4/1
x=101/22
答
X-(3/2+4/1)=12/11
X-12/11=12/11
X =12/11+12/11
X =6/11
答
X-(3/2 + 4/1)=12/11
X=12/11 + (3/2 + 4/1)
X=12/11 + 3/2 + 4
X=24/22 + 33/22 + 88/22
X=(24+33+88)/22
X=145/22
答
X-（3/2+4/1)=12/11
x-(1.5+4)=12/11
x=12/11+5.5
x=6又13/22
