Помогите!
А) |24-3х|=12
Б) |2х+30|=48
В) |-х-1|=9
Г) |2х+13|=0
Д) |3х-4|=10​

Answer 1

1) |24-3х|=12

24-3х=12 и 24-3х=-12

3х=12 и 3х=36

х=4 и х=12

2) |2х+30|=48

2х+30=48 и 2х+30=-48

2х=18 и 2х=-78

х=9 и х=-39

3) |-х-1|=9

-х-1=9 и -х-1=-9

х=-10 и х=8

4) |2х+13|=0

2х+13=0

2х=-13

х=-6,5

5) |3х-4|=10

3х-4=10 и 3х-4=-10

3х=14 и 3х=-6

х=4⅔ и х=-2
