Explicación paso a paso:

8x -  \frac{7}{2}  =  \frac{6}{5} x +  \frac{3}{5}  \\  \\ 8x -  \frac{6}{5}x =  \frac{3}{5}   +  \frac{7}{2}  \\  \\  \frac{40 - 6}{5} x =  \frac{6 + 35}{10}  \\  \\  \frac{34}{5} x =  \frac{41}{10}  \\  \\ x =  \frac{41}{10}  \div  \frac{34}{5}  \\  \\ x =  \frac{205}{340}  \\  \\ x =  \frac{41}{68}  \\ \\  comprobación \\ 8 \times  \frac{41}{68}  -  \frac{7}{2}  =  \frac{6}{5}  \times  \frac{41}{68}  +  \frac{3}{5}  \\  \\  \frac{328}{68}  -  \frac{7}{2}  =  \frac{246}{340}  +  \frac{3}{5}  \\  \\   \frac{328 - 238}{68}  =  \frac{246 + 204}{340}  \\  \\  \frac{90}{68}  =  \frac{450}{340}  \\  \\  \frac{45}{34}  =  \frac{45}{34}
