réduire l'expression E = 2x + 1/3x + 2/5 - 1/4

Bonjour,

[tex]e = 2x + \frac{1}{3} x + \frac{2}{5} - \frac{1}{4} [/tex]

[tex]e = 2x + \frac{x}{3} + \frac{2}{5} - \frac{1}{4} [/tex]

[tex]e = \frac{2x \times 3}{1 \times 3} + \frac{x}{3} + \frac{2}{5} - \frac{1}{4} [/tex]

[tex]e = \frac{6x}{3} + \frac{x}{3} + \frac{2}{5 } - \frac{1}{4} [/tex]

[tex]e = \frac{6x + x}{3} + \frac{2}{5} - \frac{1}{4} [/tex]

[tex]e = \frac{7x}{3} + \frac{2}{5} - \frac{1}{4} [/tex]

[tex]e = \frac{7x \times 5}{3 \times 5} + \frac{2 \times 3}{5 \times 3} - \frac{1}{4} [/tex]

[tex]e = \frac{35x}{15} + \frac{6}{15} - \frac{1}{4} [/tex]

[tex]e = \frac{35x + 6}{15} - \frac{1}{4} [/tex]

[tex]e = \frac{(35x + 6) \times 4}{15 \times 4} - \frac{1 \times 15}{4 \times 15} [/tex]

[tex]e = \frac{140x + 24}{60} - \frac{15}{60} [/tex]

[tex]e = \frac{(140x + 24) - 15}{60} [/tex]

[tex]e = \frac{140x + 24 - 15}{60} [/tex]

[tex]e = \frac{140x + 9}{60} [/tex]

Bonne fin de journée !
