Bonjour,
[tex]G = 4(8x - 5) = 4 \times 8x + 4 \times ( - 5) = 32x - 20[/tex]
[tex]H = \frac{3}{5} (6x + 10)[/tex]
[tex]H = \frac{3}{5} \times 6x + \frac{3}{5} \times 10 [/tex]
[tex]H = \frac{18}{5} x + \frac{30}{5} [/tex]
[tex]H = \frac{18}{5} x + 6[/tex]
[tex]I = - \frac{2}{3} (5x + \frac{7}{8}) + \frac{7}{5} x[/tex]
[tex]I = - \frac{10}{3} x - \frac{14}{24} + \frac{7}{5}x[/tex]
[tex]I = \frac{ - 10 \times 5}{3 \times 5} x + \frac{7 \times 3}{5 \times 3}x - \frac{7}{12} [/tex]
[tex]I = - \frac{50}{15}x + \frac{21}{15} x - \frac{7}{12} [/tex]
[tex]I = - \frac{29}{15} x - \frac{7}{12} [/tex]
