Математика: 1)х-7 8/11=2 5/11 2)3 7/17-(х+1 4/17)=1 9/17

skyblue1 · Answer

1) Х - 7 8/11 =2 5/11
  Х =2 5/11 + 7 8/11
  Х =10 2/11
10 2/ 11 - 7 8/11=2 5/11

2) 3 7/17 -(Х + 1 4/17) =1 9/17
Х+ 1 4/17 = 3 7/17 - 1 9/17
  Х + 1 4/17 = 1 15/17
  Х = 1 15/17 - 1 4/17
  Х =11/17
3 7/17- (11/17 +1 4/17 = 1 9/17
