\(\frac{1}{4}:x=3-\frac{3}{4}=\frac{9}{4}\)
\(x=\frac{1}{4}.\frac{4}{9}=\frac{1}{9}\)
3/4+1/4:x=-3
1/4:x=-3-3/4
1/4:x=-15/4
x=1/4:-15/4
x=-1/15
Thế mình làm đúng mà chẳng ma nào thèm tick
\(\frac{3}{4}+\frac{1}{4:x}=-3\)
\(\frac{1}{4:x}=-3-\frac{3}{4}=\frac{-15}{4}\)
\(=>\frac{1}{4:x}=\frac{-15}{4}\)
\(=>\frac{4}{x}=\frac{1\cdot4}{-15}=-\frac{4}{15}\)
\(=>x=\frac{4\cdot15}{-4}=-15\)
