Question

Решите уравнение
3 1/6 - (x + 1 1/12) = 1/4​

Answer 1

3 1/6 -( x + 1 1/12)=1/4
19/6-(x+13/12)=1/4
19/6-x-13/12=1/4
25/12-x=1/4
-x=-11/6
x=11/6
x=1 5/6

Answer 2

Пошаговое объяснение:

$\[\begin{gathered}3\frac{1}{6}-\left( {x+1\frac{1}{{12}}} \right)=\frac{1}{4} \hfill \\x+1\frac{1}{{12}}=3\frac{1}{6}-\frac{1}{4} \hfill \\x+1\frac{1}{{12}}=3\frac{2}{{12}}-\frac{3}{{12}} \hfill \\x+1\frac{1}{{12}}=2\frac{{14}}{{12}}-\frac{3}{{12}} \hfill \\ \end{gathered} \]$

$\[\begin{gathered}x+1\frac{1}{{12}}=2\frac{{11}}{{12}} \hfill \\x=2\frac{{11}}{{12}}-1\frac{1}{{12}} \hfill \\x=1\frac{{10}}{{12}}=\boxed{1\frac{5}{6}} \hfill \\ \end{gathered}\]$
