\(\dfrac{x+1}{11}-\dfrac{2x-5}{15}=\dfrac{3x-47}{17}-\dfrac{4x-59}{19}\)
\(\Leftrightarrow\left(\dfrac{x+1}{11}-1\right)-\left(\dfrac{2x-5}{15}-1\right)=\left(\dfrac{3x-47}{17}+1\right)-\left(\dfrac{4x-59}{19}+1\right)\)
\(\Leftrightarrow\dfrac{x-10}{11}-\dfrac{2\left(x-10\right)}{15}=\dfrac{3\left(x-10\right)}{17}-\dfrac{4\left(x-10\right)}{19}\)
\(\Leftrightarrow\dfrac{x-10}{11}-\dfrac{2\left(x-10\right)}{15}-\dfrac{3\left(x-10\right)}{17}+\dfrac{4\left(x-10\right)}{19}=0\)
\(\Leftrightarrow\left(x-10\right)\left(\dfrac{1}{11}-\dfrac{1}{15}-\dfrac{1}{17}+\dfrac{1}{19}\right)=0\)
\(\Leftrightarrow x-10=0\)
\(\Leftrightarrow x=10\)
Vậy x = 10
