Помогите пожалуйста срочно нужно

Answer 1

Ответ:

a) x = 3

b) x = -4

c) x = -4

d) x = 8

e) x = 5

k) x = 8

Пошаговое объяснение:

a) 3(x-3) + 2 = 8

3x - 9 + 2 = 8

3x = 15

x = 3

b) 3x - 27 = 10x + 1

7x = - 28

x = -4

c) 6(x+6) - 2 = 10

6x + 36 - 2 = 10

6x = -24

x = -4

d) 5x - 33 = 7

5x = 40

x = 8

e) -2x - 6 = 14 - 6x

4x = 20

x = 5

k) 3(x-1) + 4 = 25

3x - 3 + 4 = 25

3x = 24

x = 8
