Question

Найдите корень уравнения:
1)1/6=14
2)4x=-4/9
3)57-3x=0
4)4-x=5x+22
5)16-2x=3x
6)3x+18=5x
7)3x+38=5x+18
8)6x-45=2x-17

Answer 1

Ответ:

Объяснение:

1)

$\frac{1}{6}x=14\\ x=14*6\\x=84$

2) x = -4/9 : 4

x = -1/9

3) -3x = -57

x = 57 :3

x = 19

4) 4 - 22 = 5x + x

6x = -18

x = -3

5) 16 = 2x + 3x

5x = 16

x = 16:5

x = 3.2

6) 18 = 5x - 3x

2x = 18

x = 9

7) 38 - 18 = 5x - 3x

2x = 20

x = 10

8) 6x - 2x = 45 - 17

4x = 28

x = 7
