\(\dfrac{x-3}{x+5}=\dfrac{5}{7}\)
\(\Rightarrow7\left(x-3\right)=5\left(x+5\right)\)
\(\Rightarrow7x-21=5x+25\)
\(\Rightarrow7x-5x+21=25\)
\(\Rightarrow2x+21=25\)
\(\Rightarrow2x=25-21=4\)
\(\Rightarrow x=2\)
\(\dfrac{x-3}{x+5}=\dfrac{5}{7}\)
\(=> (x-3).7 = (x+5).5 \)
\(=> 7x-21 = 5x + 25 \)
\( => 7x -5x = 25+21 \)
\( => 2x = 46 \)
\( => x = 46 : 2 = 23\)
\(\dfrac{x-3}{x+5}=\dfrac{5}{7}\)
