Question

реши уравнение (3 3/5 -x) + 3 1/5=4 1/3 помогите сор

Answer 1

$\bigg(3\tt\displaystyle\frac{3}{5}-x\bigg)+3\frac{1}{5}=4\frac{1}{3}$

$3\tt\displaystyle\frac{3}{5}-x=4\frac{1}{3}-3\frac{1}{5}$

$3\tt\displaystyle\frac{3}{5}-x=4\frac{1*5}{3*5}-3\frac{1*3}{5*3}$

$3\tt\displaystyle\frac{3}{5}-x=4\frac{5}{15}-3\frac{3}{15}$

$3\tt\displaystyle\frac{3}{5}-x=1\frac{2}{15}$

$x=3\tt\displaystyle\frac{3}{5}-1\frac{2}{15}$

$x=3\tt\displaystyle\frac{3*3}{5*3}-1\frac{2}{15}$

$x=3\tt\displaystyle\frac{9}{15}-1\frac{2}{15}$

$x=2\tt\displaystyle\frac{7}{15}$
