\(0,0793m+\dfrac{56}{47}+100m=21\\ \Leftrightarrow0,0793m+100m=21-\dfrac{56}{47}\\ \Leftrightarrow100,0793m=\dfrac{931}{47}\\ \Rightarrow m\approx0,1979\left(2\right)\)
\(g.60\%x+\dfrac{2}{3}=\dfrac{1}{3}.6\dfrac{1}{3}\\ \Leftrightarrow60\%x+\dfrac{2}{3}=\dfrac{19}{9}\\ \Leftrightarrow60\%x=\dfrac{13}{9}\\ \Rightarrow x=\dfrac{65}{27}\)
\(b.3-\left(17-x\right)=-12\\ \Leftrightarrow17-x=15\\ \Rightarrow x=2\)
\(c.\dfrac{2}{3}x+\dfrac{1}{2}=\dfrac{1}{10}\\ \Leftrightarrow\dfrac{2}{3}x=-\dfrac{2}{5}\\ \Rightarrow x=-\dfrac{3}{5}\)
\(60\%x+0,4x+x:3=2\\ \Leftrightarrow\left(60\%+0,4+\dfrac{1}{3}\right)x=2\\ \Rightarrow\dfrac{4}{3}x=2\\ \Rightarrow x=\dfrac{3}{2}\)
Câu 1:
\(y.0,34=1,19.1,2\\ \Leftrightarrow y.0,34=1,428\\ \Rightarrow x=4,2\)
Câu 2:
\(0,2:y=\dfrac{1}{2}-4.5\\ \Leftrightarrow0,2:y=-4\\ \Rightarrow y=-0,05\)
