Bonjour,
Exercice 1 :
2x-23=9x-2 <=> 2x-9x=-2+23
<=> -7x=21
<=> x=-3
3-5t=10-12t <=> 3-10=-12t+5t
<=> -7=-7t
<=> t=1
4x+13=22+7x <=> 4x-7x=22-13
<=> -3x=9
<=> x=-3
-3a-1=2(a+7) <=> -3a-1=2a+14
<=> -3a-2a=14+1
<=> -5a=15
<=>
a=-3
Exercice 2 :
Soit x la longueur en km d'un tour de circuit :
Trajet de A :
A=3x+0.4
Trajet de B :
B=x+1.4
