Question

ПОМОГИТЕЕ!!(с объяснением)

Answer 1

1. Б

3|x|-1 = 14

3|x| = 15

|x| = 5

x = ±5

2.Г

(3x-2)(x+4) = 0

[3x-2 = 0

[x+4 = 0; x = -4

3x = 2

x = 2/3

3. В

-3(x-1) = 4x+11

-3x-3 = 4x+11

4x+3x = 3-11

7x = -14

x = -2

4. Д

x-5(6-x) = 2x-2

x-30+5x = 2x-2

6x-2x = -2+30

4x = 28

x = 7
