Bonsoir :)
2x + 1 = 8x - 2
2x - 8x = -2 - 1
-6x = -3
[tex]x = \frac{3}{6} = \frac{1}{2}[/tex]
8 - 2x = 4x + 2
8 - 2 = 4x + 2x
6 = 6x
[tex]x = \frac{6}{6} = 1[/tex]
2(4x + 1) = 3(x + 0)
8x + 2 = 3x + 0
8x - 3x = 0 - 2
5x = -2
[tex]x = \frac{-2}{5}[/tex]
5(2x - 1) = 10x - 1
10x - 5 = 10x - 1
10x - 10x = -1 + 5
0x = 4 => IMPOSSIBLE car {0x}
