|4х-3|=0, |4-5х|=0 и |9х+2|-3³=(-3)³

Прошу помощи у Модераторов

Answer 1

$displaystyle |4x-3|=0\\4x-3=0\\4x=3\\x=3/4$

$displaystyle |4-5x|=0\\4-5x=0\\4=5x\\x=4/5$

$displaystyle |9x+2|-3^3=(-3)^3\\|9x+2|-27=-27\\|9x+2|=-27+27\\9x+2=0\\9x=-2\\x=-2/9$

Answer 2

|4x-3|=0;
4х-3=0
4х=3
х=3/4

|4-5x|=0;
4-5х=0
5х=4
х=0,8

|9x+2|-3³ =(-3)³
|9x+2|-27 =-27
|9x+2| =-27+27
|9x+2| =0
9х+2=0
9х=-2
х=-2/9
