Question

2436 x(5 . x + 103)=12

Answer 1

\(2436\cdot\left(5\cdot x+103\right)=12\)

\(5\cdot x+103=2436:12=203\)

\(5\cdot x=203-103=100\)

\(x=100:5=20\)

Answer 2

\(2436.\left(5x+103\right)=12\)

\(5x+103=12:2436\)

\(5x+103=12:2436\)

\(5x+103=\frac{1}{2003}\)

\(5x=\frac{1}{2003}-103\)

\(5x=\frac{-206308}{2003}\)

\(x=\frac{-206308}{2003}.\frac{1}{5}\)

\(x=\frac{-206308}{10015}\)

Answer 3

\(2436\times\left(5\times x+103\right)=12\)

\(\Rightarrow5\times x+103=12:2436\)

\(\Rightarrow5\times x+103=\frac{1}{203}\)

\(\Rightarrow5\times x=\frac{1}{203}-103\)

\(\Rightarrow5\times x=-\frac{20908}{203}\)

\(\Rightarrow x=-\frac{20908}{203}:5\)

\(\Rightarrow x=...\)

Bn tự tính nha !
