Question

Найдите два корня уравнения.

|-0.63|:|x|=|-0.91|

Answer 1

|x|=±|-0.63|/|-0.91|

x=±0.69231

Answer 2

|-0.63|:|x|=|-0.91|

 |-0.63| =0.63

  |-0.91|=0.91

 |-0.63|:|x|=|-0.91| => 0.63 /|x|=  0.91

 0.63 /|x|=  0.91  - домножимо на |х|

0.63=0.91|x|

|x|= 9/13

x>=0               x<=0 

x= 9/13          x= -9/13
