( x + \(\frac{1}{8}\)) : \(\frac{2}{3}\)= 3 - \(\frac{3}{4}\)
( x + \(\frac{1}{8}\)) : \(\frac{2}{3}\)= \(\frac{12}{4}\)- \(\frac{3}{4}\)
( x + \(\frac{1}{8}\) ) : \(\frac{2}{3}\)= \(\frac{9}{4}\)
x + \(\frac{1}{8}\) = \(\frac{9}{4}\)x \(\frac{2}{3}\)
x + \(\frac{1}{8}\) = \(\frac{3}{2}\)
x = \(\frac{3}{2}\)- \(\frac{1}{8}\)
x = \(\frac{11}{8}\)
Chúc bn hok tốt ~
À, mik bt phần 1 thôi nhé. Phần kia mik ko bt. Mong bn thông cảm nhé
\(\left(x+\frac{1}{8}\right):\frac{2}{3}=3-\frac{3}{4}\)
\(\left(x+\frac{1}{8}\right):\frac{2}{3}=\frac{9}{4}\)
\(x+\frac{1}{8}=\frac{3}{2}\)
\(x=\frac{11}{8}\)
quên mất còn b, chắc cận rồi (hihi)
\(\frac{4}{x}=\frac{-y}{6}=0,5\)
Xét : \(\frac{4}{x}=0,5\Leftrightarrow x=2\)
Xét : \(\frac{-y}{6}=0,5\Leftrightarrow-y=3\Leftrightarrow y=-3\)
\(\left(x+\frac{1}{8}\right):\frac{2}{3}=3-\frac{3}{4}\)
\(\Leftrightarrow\left(x+\frac{1}{8}\right):\frac{2}{3}=\frac{9}{4}\)
\(\Leftrightarrow x+\frac{1}{8}=\frac{9}{4}.\frac{2}{3}\)
\(\Leftrightarrow x+\frac{1}{8}=\frac{3}{2}\)
\(\Leftrightarrow x=\frac{3}{2}-\frac{1}{8}\)
\(\Leftrightarrow x=\frac{11}{8}\)
Vậy\(x=\frac{11}{8}\)
\(\frac{4}{x}=\frac{-y}{6}=0,5\)
Ta có:\(\frac{4}{x}=0,5\)
\(\Rightarrow x=8\)
\(\frac{-y}{6}=0,5\)
\(\Rightarrow y=-3\)
Vậy\(x=8;y=-3\)
