Решите уравнение

(4*b-16) : 2=10

(2+x:7) * 8=72

35: (15-y:8) = 5

(t*3+5) : 4=8

(4*b - 16) : 2 = 10

4b - 16 = 10*2

4b - 16 = 20

4b=20 + 16

4b=36

b=36:4

b=9

проверим:

(4*9 - 16) : 2 = 10

(36-16) : 2=10

20:2 = 10

10=10

(2+х: 7) * 8 = 72

2+х: 7 = 72:8

2+х: 7 = 9

х: 7 = 9-2

х: 7 = 7

х=7*7

х=49

(2+49:7) * 8=72

(2+7) * 8=72

9*8 = 72

72=72

35: (15 - у: 8) = 5

15 - у: 8 = 35:5

15 - у: 8 = 7

у: 8 = 15 - 7

у: 8 = 8

у=8*8

у=64

35: (15 - 64:8) = 5

35: (15-8) = 5

35: 7 = 5

5=5

(t * 3 + 5) : 4 = 8

3t + 5 = 8*4

3t + 5 = 32

3t = 32-5

3t = 27

t=27:3

t=9

(9*3 + 5) : 4 = 8

(27+5) : 4 = 8

32:4 = 8

8=8
