❗СРОЧНО❗​

Answer 1

Пошаговое объяснение:

1. 6X-11= x + 14

5x = 25

x = 5

2. 5(6x-1)= 3x-5

30x - 5 = 3x - 5

27x = 0

x = 0

3. 5+3(7x + 4) = 6x-13

5 + 21x + 12 = 6x - 13

15x = -30

x = -2

4. 5(3x + 4)-6(3x-7)= 23x

15x + 20 - 18x + 42 = 23x

-26x = -62

x = 31/13

5. 4(5x-3)-5(3x + 7) = 6x-23

20x - 12 - 15x - 35 = 6x - 23

-x = 24

x = -24

6. 2(x+21) + 3(x-4)= 5(x+6)

2x + 42 + 3x - 12 = 5x + 30

0 = 0

x = R (любое число)
