Bonsoir
Exercice 1
a) 2(x-3) - (2x+1)
⇒ 2x - 6 - 2x -1 =
-7
b) (-x +4)(2x -1)
⇒ -2x² +x +8x - 4 =
-2x² +9x -4
c) -2x (x-4) - ( -x +4)
⇒ -2x² +8x +x -4
= - 2x² +9x -4
Exercice
2
a) 1 -2 (t -5) = 3(2 -4t)
⇒ 1 - 2t +10 = 6 - 12t
⇒ -2t +12t = 6 - 1 -10
⇒ 10t = -5 ⇒ t = -5/10 =
-1/2
b) -3x/3 = 7/5
⇒ -15x = 21 ⇒ x = -21/15 =
- 7/5
