Question

1. (X + 35). 3 = 207
2. 5. (x - 20) = 455
3. (23 + x). 15 = 450
4. (X - 56):11 = 4
5. (x + 123) : 9 = 22
6. (29-x) : 3 = 9​

Answer 1

Ответ:

1. X+35=207:3

X+35=69

X=69-35

X=34

2. X-20=455:5

X-20=91

X=91+20

X=111

3. 23+x=450:15

23+x=30

X=30-23

X=7

4. X-56=4•11

X-56=44

X=56+44

X=100

5. X+123=22•9

X+123=198

X=198-123

X=75

6. 29-x=9•3

29-x=27

X=29-27

X=2
