COMMENCER
2x + 4 = 4x + 2
x = -3
x = 1
a pour solution...
Solution
2x + 4 = 4x + 2 2x - 4x = 2 - 4 -2x = -2 x = -2/-2 x = 1
2x + 4 = 4x + 2
x = 1
a pour solution...
x = -1/3
x = 1
3x + 1 = 2x + 2
a pour solution...
Solution
3x + 1 = 2x + 2 3x - 2x = 2 - 1 x = 1
x = 1
3x + 1 = 2x + 2
a pour solution...
x = 6
4x - 4 = 2x + 8
x = -2
a pour solution...
Solution
4x - 4 = 2x + 8 4x - 2x = 8 + 4 2x = 12 x = 12/2 x = 6
4x - 4 = 2x + 8
x = 6
a pour solution...
x = -3
6x + 2 = 4x - 4
x = -1
a pour solution...
Solution
6x + 2 = 4x - 4 6x - 4x = - 4 - 2 2x = -6 x = -6/2 x = -3
6x + 2 = 4x - 4
x = -3
a pour solution...
x = -7
x = -1
5x + 5 = 4x - 2
a pour solution...
Solution
5x + 5 = 4x - 2 5x - 4x = -2 - 5 x = -7
5x + 5 = 4x - 2
x = -7
a pour solution...
x = 10/3
-x + 4 = 2x - 6
x = 4
a pour solution...
Solution
-x + 4 = 2x - 6 -x - 2x = -6 - 4 -3x = -10 x = -10/-3 x = 10/3
x = 10/3
-x + 4 = 2x - 6
a pour solution...
x = -2.5
x = 0
2x + 6 = -2x - 4
a pour solution...
Solution
2x + 6 = -2x - 4 2x + 2x = - 4 - 6 4x = -10 x = -10/4 x = -2.5
x = -2.5
2x + 6 = -2x - 4
a pour solution...
x = -5
-3x - 9 = -2x - 4
x = -3
a pour solution...
Solution
-3x - 9 = -2x - 4 -3x + 2x = - 4 + 9 -x = 5 x = -5
x = -5
-3x - 9 = -2x - 4
a pour solution...
x = 0
x + 4 = 2x + 4
x = -4
a pour solution...
Solution
x + 4 = 2x + 4 x - 2x = 4 - 4 -x = 0 x = 0
x = 0
x + 4 = 2x + 4
a pour solution...
-x + 16 = -2x + 8
x = -8
x = -2
a pour solution...
Solution
-x + 2x = 8 - 16 x = - 8
-x + 16 = -2x + 8
x = -8
a pour solution...
