Question

|5x-4|+6=9 РЕШИТЕ СРОООЧНО ПЖ
​

Answer 1

Ответ:

|5x-4|=9-6

|5x-4|=3

5x-4=3

5x-4=-3

x1=7/5= x1=1,4

x2=1/5= x2=0,2

Answer 2

Ответ:

$|5x - 4| + 6 = 9$

$|5x - 4| = 9 - 6$

$|5x - 4| = 3$

$5x - 4 = 3$

$5x = 3 + 4$

$5x = 7$

1)

$x = \frac{7}{5} = 1.4$

$5x - 4 = - 3$

$5x = - 3 + 4$

$5x = 1$

2)

$x = \frac{1}{5} = 0.2$

Ответ: х1 = 1.4; х2 = 0.2
