Bonsoir
résoudre les équations suivantes en détaillant les différentes étapes,vous donnerez le résultat sous forme de nombre entier ou décimal ou sous forme de fractions irréductibles
4x - 24 = 0
4x - 24 + 24 = 0 + 24
4x = 24
4x/4 = 24/4
x = 6
x + 3 = -7
x = -7 - 3
x = -10
6x = 24
6x/6 = 24/6
x = 4
-5x = 30
-5x/(-5) = 30/(-5)
x = -6
7 - x = 8
x = 7 - 8
x = -1
5x = 2x + 9
5x - 2x = 9
3x = 9
x = 9/3
x = 3
3x + 1 = x + 13
3x - x = 13 - 1
2x = 12
x = 12/2
x = 6
4x + 7 - 5x = -9 + 3x
-x + 7 = -9 + 3x
7 + 9 = 3x + x
16 = 4x
x = 16/4
x = 4
-3x/5 = -18/100
3x/5 = 18/100
x = 18/100 * 5/3
x = 18/3 * 5/100
x = 6 * 5/(5 x 20)
x = 6 * 1/20
x = 6/20
x = (2 * 3)/(2 * 10)
x = 3/10
x = 0,3
2(x - 12) = 4 - 2(5x - 4)
2x - 24 = 4 - 10x + 8
2x + 10x = 12 + 24
12x = 36
x = 36/12
x = 3
