Aflati x Apartine Q :

a) 5/4x+1/3X=1/12

Answer 1

$\frac{5}{4} x+ \frac{1}{3} x= \frac{1}{12} \Longleftrightarrow \frac{15}{12} x+ \frac{4}{12} x= \frac{1}{12} \Longleftrightarrow \frac{19}{12} x= \frac{1}{12} \Longleftrightarrow \\ \Longleftrightarrow x= \frac{1}{12} : \frac{19}{12} = \frac{1}{12} \cdot \frac{12}{19} =\boxed{ \frac{1}{19}}$
