Answer 1

Răspuns:

Explicație pas cu pas:

a)

$x + \frac{3}{5} = \frac{11}{5}$

$x = \frac{11}{5} - \frac{3}{5} = \frac{8}{5}$

b)

$\frac{12}{17} - x = \frac{15}{34}$

$- x = \frac{15}{34} - \frac{ {}^{2)} 12}{17}$

$- x = \frac{15}{34} - \frac{24}{34} = - \frac{9}{34} \rightarrow x = \frac{9}{34}$

c)

$x - \frac{8}{3} = \frac{1}{24}$

$x = \frac{1}{24} + \frac{ {}^{8)} 8}{3} = \frac{1}{24} + \frac{64}{24} = \frac{65}{24}$
