Answer 2

1. x + 75 = 87 x = 87 - 75 x = 12

2. 136 - x = 107 x = 136 - 107 x = 29

3. 555/5 - x = 74 111 - x = 74 x = 111 - 74 x = 37

4. 2x + 87 = 93 2x = 93 - 87 2x = 6 x = 3

5. 105 - 3x = 63 3x = 105 - 63 3x = 42 x = 14

6. (120 - x)/13 = 8 120 - x = 104 x = 120 - 104 x = 16

Ответы:

1. x = 12
2. x = 29
3. x = 37
4. x = 3
5. x = 14
