1-x÷3=2(1-x÷2)3(x+2)=4(x+1)81x-342=76(x-2)x÷2+x÷3=0.51-x÷3=2(1-x÷2)3(x+2)=4(x+1)81x-342=76(x-2)x÷2+x

1-x÷3=2(1-x÷2) 3(x+2)=4(x+1) 81x-342=76(x-2) x÷2+x÷3=0.5
1-x÷3=2(1-x÷2) 3(x+2)=4(x+1) 81x-342=76(x-2) x÷2+x÷3=0.5

1-x÷3=2(1-x÷2) 3(x+2)=4(x+1) 81x-342=76(x-2) x÷2+x÷3=0.5
不好意思,你写的式子应该是多个方程吧,我就按我理解的给你解答了
1-x÷3=2(1-x÷2) 3(x+2)=4(x+1) 81x-342=76(x-2) x÷2+x÷3=0.5
1-x/3=2-x x=2 5x=190 x=3/5
x=3/2 x=38
