Question

Решите уравнения 1)6x=36 2)5x=5\7 3)-x=18 4)11x=-1\3 5)49x=0 6)21x=-3 6)-3\7x=-1

Answer 1

1)6x=36
x = 6
Ответ:х = 6
2)5x=5\7
х = 1/7
Ответ: х = 1/7
3)-x=18
х = -18
Ответ: х = -18
4)11x=-1\3
х = - 1/33
Ответ : х = - 1/33
5)49x=0
х = 0
Ответ : х = 0
6)21x=-3
х = -1/7
Ответ : х = -1/7
7)-3\7x=-1
х = 7/3 = 2 целых 1/3
Ответ : х = 2 целых 1/3.

Answer 2

1. 6x = 36 Dividing both sides by 6, we get: x = 6

2. 5x = 5/7 Dividing both sides by 5, we get: x = 1/7

3. -x = 18 Multiplying both sides by -1, we get: x = -18

4. 11x = -1/3 Dividing both sides by 11, we get: x = -1/33

5. 49x = 0 Dividing both sides by 49, we get: x = 0

6. 21x = -3 Dividing both sides by 21, we get: x = -3/21 = -1/7

7. (-3/7)x = -1 Multiplying both sides by -7/3, we get: x = 7/3
