tukacheva88 · Answer

10*(1,37k-0,12k):5:8=0

1,37к-0,12к=0

к(1,37-1,12)=0

к=0

(0,87m-0,66m)*10:2:3=0

0,87m-0,66m=0

m(0,87-0,66)=0

m=0

(15b+b):4=3

15b+b=0

16b=0

b=0

(7a-2a)*8=80

7а-2а=80:8

5а=10

а=10:5

а=2

14y-2y+76=100

14у-2у=100-76

12у=24

у=24:12

у=2

22x+x-10=59

22х+х=59+10

23х=69

х=69:23

х=3
