1、88%x- 10=22%x

2、 120% x+20% x = 60% x+ 100% x

3、 10%x+20%x+30%x=40

4、32%x=22%x+ 10

5、67- 12%x=57- 10%x

6、 16%x= 18%x

7、200%x-23-(23-200%x)=23

8、 103%x=88+3%x

9、60%x-30=30%x- 10

10、x+70%x=340

1 1、 170%x=340

12、2/3+75%x=64%

13、x-60%x=3.6

14、 150+30%x=450

15、63%+x=75

16、46x- 12%+2=56

17、 10%x-30+20%x-60=30

18、 162.5%-x = 15/ 16

19、X- 18%X=0.82

20、40%-2 1=37
