\(1.x+\dfrac{1}{4}=\dfrac{4}{3}\\ x=\dfrac{4}{3}-\dfrac{1}{4}\\ x=\dfrac{16}{12}-\dfrac{3}{12}=\dfrac{13}{12}\)
1) \(x=\dfrac{4}{3}-\dfrac{1}{4}\Rightarrow x=\dfrac{13}{12}\)
2) \(\dfrac{2}{5}x=\dfrac{-4}{15}\Rightarrow x=\dfrac{-2}{3}\)
3) \(\dfrac{7}{4}x+\dfrac{3}{2}=\dfrac{-4}{5}\Rightarrow\dfrac{7}{4}x=\dfrac{-23}{10}\Rightarrow x=\dfrac{-46}{35}\)
1) \(x+\dfrac{1}{4}=\dfrac{4}{3}\)
\(x\) \(=\dfrac{4}{3}-\dfrac{1}{4}\)
\(x\) \(=\dfrac{13}{12}\)
2) \(\dfrac{3}{4}+\dfrac{2}{5}x=\dfrac{29}{60}\)
\(\dfrac{2}{5}x=\dfrac{29}{60}-\dfrac{3}{4}\)
\(\dfrac{2}{5}x=-\dfrac{4}{15}\)
\(x=\left(-\dfrac{4}{15}\right):\dfrac{2}{5}\)
\(x=-\dfrac{2}{3}\)
3) \(1\dfrac{3}{4}.x+1\dfrac{1}{2}=-\dfrac{4}{5}\)
\(x+1\dfrac{1}{2}=\left(-\dfrac{4}{5}\right):1\dfrac{3}{4}\)
\(x+1\dfrac{1}{2}=-\dfrac{16}{35}\)
\(x=\left(-\dfrac{16}{35}\right)-\dfrac{3}{2}\)
\(x=-\dfrac{137}{70}\)
