Answer 1

Răspuns:

a) x = 3/5

b) x = 1/3

c) x = 3/5

Explicație pas cu pas:

22.

a)

$\frac{7}{5} -\frac{8}{5} +x=\frac{2}{5}$

$-\frac{1}{5} +x =\frac{2}{5}$

$x=\frac{2}{5} +\frac{1}{5} =\frac{3}{5}$

b)

$\frac{8}{3} +\frac{4}{3} -x-\frac{3}{3} =\frac{8}{3}$

$\frac{9}{3} -x=\frac{8}{3}$

$x=\frac{9}{3} -\frac{8}{3}=\frac{1}{3}$

c)

$\frac{2}{5} +\frac{2}{5} +\frac{2}{5} -x-\frac{1}{5} =\frac{3}{5}$

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

$x=\frac{5}{5} -\frac{3}{5} =\frac{2}{5}$
