Question

(х - 1 1/10) + 4 1/5 = 5 1/3​

Answer 1

Решение и ответ:

$\displaystyle \left({x-1\frac{1}{{10}}}\right)+4\frac{1}{5}=5\frac{1}{3}$

$\displaystyle \left({x-1\frac{1}{{10}}}\right)=5\frac{1}{3}-4\frac{1}{5}$

$\displaystyle x-1\frac{1}{{10}}=5\frac{5}{{15}}-4\frac{3}{{15}}$

$\displaystyle x-1\frac{1}{{10}}=(5-4)+\left({\frac{5}{{15}}-\frac{3}{{15}}}\right)$

$\displaystyle x-1\frac{1}{{10}}=1+\frac{2}{{15}}$

$\displaystyle x-1\frac{1}{{10}}=1\frac{2}{{15}}$

$\displaystyle x=1\frac{2}{{15}}+1\frac{1}{{10}}$

$\displaystyle x=1\frac{4}{{30}}+1\frac{3}{{30}}$

$\displaystyle x=(1+1)+\left({\frac{4}{{30}}+\frac{3}{{30}}}\right)$

$\displaystyle x=2+\frac{7}{{30}}$

$\displaystyle \boxed{x=2\frac{7}{{30}}}$
