2/15+9/15+x=123/6=z-15/6+17/6Urgent va rog!!! .... Idea question from @blackrose63

Răspuns:

$\frac{2}{15} + \frac{9}{15} + x = 1$

$\frac{2 + 9}{15} + x = 1$

$\frac{11}{15} + x = 1$

$x = 1 - \frac{11}{15}$

$x = \frac{15}{15} - \frac{11}{15}$

$x = \frac{15 - 11}{15}$

$x = \frac{4}{15}$

$\frac{23}{6} = z - \frac{15}{6} + \frac{17}{6}$

$\frac{23}{6} = z + \frac{ - 15 + 17}{6 }$

$\frac{23}{6} = z + \frac{2}{6}$

$\frac{23}{6} = z + \frac{1}{3}$

$- z = \frac{1}{3} - \frac{23}{6}$

$- z = \frac{2}{6} - \frac{23}{6}$

$- z = \frac{2 - 23}{6}$

$- z = \frac{ - 21}{6}$

$- z = - \frac{7}{2}$

$z = \frac{7}{2}$

Sper ca te am ajutat!
