五分之x+4-(x-5)=二分之x+3 x-二分之x-1=2-五分之x+2
x/5+4-(x-5)=x/2+3
2x+40-10(x-5)=5x+30
2x+40-10x+50=5x+30
2x-10x-5x=30-40-50
-13x=-60
x=60/13
x-二分之x-1=2-五分之x+2
x-x/2-1=2-x/5+2
x-x/2+x/5=2+2+1
(10x-5x+2x)10=5
7x=1/2
x=1/14
3(t+1)-三分之一(t-1)=2(t-1)-二分之一(t+1)
3(t+1)-(t-1)/3=2(t-1)-(t+1)/2
18(t+1)-2(t-1)=12(t-1)-3(t+1)
18t+18-2t+2=12t-12-3t-3
18t-2t-12t+3t=-12-3-18-2
7t=-35
t=-5
2x-3(10-x)=5x-7(x+3)
2x-30+3x=5x-7x-21
2x+3x-5x+7x=-21+30
7x=9
x=9/7
三分之2x+1减六分之5x-1=1
2x/3+1-5x/6-1=1
4x/6-5x/6=1-1+1
-x/6=1
x=-6
