( P.s _ это значит черта, ( дробная.) срочно, помогите!

Answer 1

15 3/8 : ( 2 3/4 x + 5 5/6) - 1 1/2 = 3/4
15 3/8 : ( 2 3/4 x + 5 5/6) = 3/4 + 1 1/2
15 3/8 : ( 2 3/4 x + 5 5/6) = 3/4 + 1 2/4
15 3/8 : ( 2 3/4 x + 5 5/6) = 1 5/4
15 3/8 : 2 1/4 = 2 3/4 x + 5 5/6
123/8 : 9/4 = 2 3/4 x + 5 5/6
123/8 * 4/9 = 2 3/4 x + 5 5/6
41/2*3 = 2 3/4 x + 5 5/6
41/6 - 5 5/6 = 2 3/4 x
6 5/6 - 5 5/6 = 2 3/4 х
1 = 11/4х
х= 1 : 11/4
х= 1 * 4/11
х= 4/11

Answer 2

х= 1 : 11/4
х= 1 * 4/11
х= 4/11
Ответ: 4/11
