Sagot :
1)
3/7 + x = 2
donc x = 2-3/7=14/7-3/7=11/7
Il faut ajouter 11/7.
2)
3/1+1/4+1/6+x=1
donc x=1-3/1-1/4-1/6=12/12-36/12-3/12-2/12=-29/12
3)
x*3/11=-2
donc x=-2*11/3=-22/3
3/7 + x = 2
donc x = 2-3/7=14/7-3/7=11/7
Il faut ajouter 11/7.
2)
3/1+1/4+1/6+x=1
donc x=1-3/1-1/4-1/6=12/12-36/12-3/12-2/12=-29/12
3)
x*3/11=-2
donc x=-2*11/3=-22/3
1) 3/7 + x= 2
x = 2 - 3/7
x = 11/7
2) 3/1 + 1/4 + 1/6 + x = 1
x = 1- ( 3/1 + 1/4 + 1/6 )
x = -29 / 12
3) x * 3/11 = -2
x = -2 / (3/11)
x = -22/3
