Question

3х-7/4-9х+11/8=3-х/2

Answer 1

3х-7/4-9х+11/8=3-х/2

3х - 7/4 - 9х + 11/8 = 3 - х/2 ;

3х - 9х + х/2 = 3 + 7/4 + 11/8 ; 6х + х/2 = 3 + 14/8 + 11/8 ;

-6х/1 + х/2 = 3 + 25/8 ; - 12х + х )/2 = 3 + 3 целых и 1/8 ;

- 11х/2 = 6 целых и 1/8 ;

- 11х/2 = 49/8 ;

- 11х = 49/4 ;

х = 49/4 : ( - 11 ) ;

х = 1 целая 5/44.
