\(4.\left(\frac{1}{2}-3\right)-6.\left(\frac{5}{6}x+2\right)=0\)
\(4.\left(\frac{1}{2}-\frac{6}{2}\right)-6.\left(\frac{5}{6}x+2\right)=0\)
\(4.\frac{-5}{2}-6.\left(\frac{5}{6}x+2\right)=0\)
\(-10-6.\left(\frac{5}{6}x+2\right)=0\)
\(6.\left(\frac{5}{6}x+2\right)=-10-0\)
\(6.\left(\frac{5}{6}x+2\right)=-10\)
\(\frac{5}{6}x+2=0:6\)
\(\frac{5}{6}x+2=0\)
\(\frac{5}{6}x=0-2\)
\(\frac{5}{6}x=-2\)
\(x=-2:\frac{5}{6}\)
\(x=-2.\frac{6}{5}\)
\(x=\frac{-12}{5}\)
Vậy \(x=\frac{-12}{5}\)
Chúc bn học tốt !
\(4\left(\frac{1}{2}-3\right)-6\left(\frac{5}{6}x+2\right)=0\)
\(4.\frac{-5}{2}-6\left(\frac{5}{6}x+2\right)=0\)
\(-10-6\left(\frac{5x}{6}+2\right)=0\)
\(6\left(\frac{5x}{6}+2\right)=-10\)
\(\frac{5x}{6}+2=-\frac{5}{3}\)
\(\frac{5x}{6}=-\frac{11}{3}\)
\(\frac{5x}{6}=-\frac{22}{6}\)
\(5x=-22\)
\(x=-\frac{22}{5}\)
