Question

Решите уравнение: 4 |2х-3| - 24 = 12

Answer 1

4 |2х-3| - 24 = 12

4 |2х-3| = 12 + 24

4 |2х-3| = 36

|2х-3| = 9 |2х-3| = -9

х = 6 х = -3

Answer 2

Ответ:

$4 |2x - 3| - 24=12$

$4 |2x - 3| = 12 + 24$

$4 |2x - 3| = 36$

$|2x - 3| = 36 \div 4$

$|2x - 3| = 9$

1)2x-3=9

2x=9+3

x=6

2)2x-3=-9

2x=3-9

x=-3

x1=6; x2=-3.
