Question

помогите плиз!!!
3/2 (2x+2/3)-4/5=2

Answer 1

3/2 *(2x +2/3) -4/5  = 2 ;
3/2 *(2x +2/3)  =4/5 + 2 ;
3/2 *(2x +2/3)  =14/5  ;
2x +2/3 = 14/5 : 3/2 ;
2x +2/3 = 28/15  ; 
2x = 28/15  - 2/3  ;
2x = 18/15 ;  
2x = 6/5  ;
x =  6/5 : 2 ;
x =3/5 .   ***  x = 0,6 ***

*******   или  *********************
3/2 *(2x +2/3)  -4/5 = 2  ;
3/2 *2x + 3/2 *2/3  -4/5 =2 ;
3 x+ 1 - 4/5  =2;
3x +1/5 =2;
3x = 2 -1/5 ;
3x =9/5 ;
x = 3/5 .
