:\(199,5:\frac{\frac{3}{5}\cdot X+4}{20}+8,5=\frac{242}{5}\)

 

Answer 1

Đề :

\(199,5:\frac{\frac{3}{5}\cdot x+4}{20}+8,5=\frac{242}{5}\)

\(\Rightarrow199,5:\frac{\frac{3}{5}\cdot x+4}{20}=\frac{242}{5}-8,5\)

\(\Rightarrow199,5:\frac{\frac{3}{5}\cdot x+4}{20}=48,4-8,5\)

\(\Rightarrow199,5:\frac{\frac{3}{5}\cdot x+4}{20}=39,9\)

\(\Rightarrow\frac{\frac{3}{5}\cdot x+4}{20}=199,5:39,9\)

\(\Rightarrow\frac{\frac{3}{5}\cdot x+4}{20}=5\)

\(\Rightarrow\frac{3}{5}\cdot x+4=5\cdot20\)

\(\Rightarrow\frac{3}{5}\cdot x+4=100\)

\(\Rightarrow\frac{3}{5}x=96\Leftrightarrow x=160\)

Answer 2

biến đổi là ra x = 160 thôi

Answer 3

la sao bn
