Exercice 5 :
a) 7(-3x + 5)

= -21x +35
b) -5(-2x+4)
= -5*(-2x) + (-5)*4
=10x - 20
c) 2-3 (5x-7)
= -1 (5x-7)
= -1*5x + (-1) * (-7)

A =7(-3x+5) = -21x +35
b = -5(-2x+4) = 10x -20
c = 2 -3(5x-7) = 2 -15x+21 = -15x +23
d= 4(-2x+1) -3(7x-2) = -8x+4 -21x+6 = -29x +10
2/
a = -3(x-1.7) -5y
a = -3(-2.3-1.7) -5*-4
a = -3( -4) +20
a = 12 +20
a = 32
a = -3(x-1.7) -5y
a = -3x + 5.1 -5y
a = -3*-2.3 +5.1 -5(-4)
a = +6.9 +5.1 +20
