Bonjour,
[tex] - 29x + 11 = 4x + ( - 1)[/tex]
[tex] - 29x + 11 = 4x - 1[/tex]
[tex] - 29x +29x + 11 = 4x + 29x - 1[/tex]
[tex]33x - 1 = 11[/tex]
[tex]33x - 1 + 1 = 11 + 1[/tex]
[tex]33x = 12[/tex]
[tex] \frac{33x}{33} = \frac{12}{33} [/tex]
[tex]x = \frac{12}{33} [/tex]
[tex]x = \frac{3 \times 4}{3 \times 11} [/tex]
[tex]x = \frac{4}{11} [/tex]
