\(\frac{1}{4}+\frac{1}{3}:3x=-5\)
\(\Rightarrow\frac{1}{9x}=\frac{-21}{4}\)
\(\Rightarrow-189x=4\)
\(\Rightarrow x=-\frac{4}{189}\)
1/4 + 1/3 :3x= -5
=> 1/3 : 3x= (-5) - 1/4 = -21/4
=> 3x = -4/63
=> x = -4/189
nhớ cho mk nha
\(\frac{1}{4}+\frac{1}{3}:3x=-5\)
\(=\frac{1}{4}+\frac{1}{\frac{3}{3}}x=-5\)
\(=\frac{1}{4}+\frac{1}{9}x=-5\)
\(=\frac{1}{9}x=\left(-5\right)-\frac{1}{4}\)
\(=\frac{1}{9}x=-\frac{21}{4}\)
\(=x=9.\left(-\frac{21}{4}\right)\)
\(=x=-\frac{189}{4}\)
\(\Rightarrow x=-\frac{189}{4}\)
