Bonjour,
x-5/4 = 4/3
x= 4/3 + 5/4 = 16/12 +15/12 = 31/12
x+ 7/3 =5/7
x= 5/7 -7/3 = 15/21 - 49/21 = -34/21
x-5/8 = 3/12
x= 3/12 +5/8 = 6/24 + 15/24 = 21/24 = 7/8
1/3 -x = -2/9
1/3 +2/9 = x
3/9 +2/9 = x
x= 5/9
5/18 -x =11/45
5/18 -11/45 = x
25/90 -22/90 = x
x= 3/90 = 1/30
x-12/25 = -11/15
x= -11/15 +12/25
x= -275/ 375 + 180/375 = -95/375 = -19/75
