\(2436\cdot\left(5\cdot x+103\right)=12\)
\(5\cdot x+103=2436:12=203\)
\(5\cdot x=203-103=100\)
\(x=100:5=20\)
\(2436.\left(5x+103\right)=12\)
\(5x+103=12:2436\)
\(5x+103=12:2436\)
\(5x+103=\frac{1}{2003}\)
\(5x=\frac{1}{2003}-103\)
\(5x=\frac{-206308}{2003}\)
\(x=\frac{-206308}{2003}.\frac{1}{5}\)
\(x=\frac{-206308}{10015}\)
\(2436\times\left(5\times x+103\right)=12\)
\(\Rightarrow5\times x+103=12:2436\)
\(\Rightarrow5\times x+103=\frac{1}{203}\)
\(\Rightarrow5\times x=\frac{1}{203}-103\)
\(\Rightarrow5\times x=-\frac{20908}{203}\)
\(\Rightarrow x=-\frac{20908}{203}:5\)
\(\Rightarrow x=...\)
Bn tự tính nha !
