Résoudre les équations suivantes
8(x-2) = 16 = 8*x + 8*(-2) = 16
8x - 16 = 16
8x = 16 + 16
x = 32/8 = 4
32 x (x+4)= 52
32*x + 32*4 = 52
32x + 128 = 52
32x = 52 - 128
x = -76/32
x = - 2,375
- 2 (-3x-6)=-8
-2*(-3x) - 2*(-6) = -8
6x + 12 = -8
6x = -8-12
x = -20/6
x = -10/3
- 2/3 (2x-1) = -2
-2/3*2x - 2/3*(-1) = -2
-4/3x + 2/3 = -2
-4/3x = -2 - 2/3
-4/3x = -6/3 - 2/3
-4/3x = -8/3
x = 8/3 * 3/4
x = 2
