The correct answer is "x = 29/5".

Step-by-step explanation:

The \ given \ expression \ is:\\\\\frac{2}{5x+5}=\frac{3}{10x-7}\\  \\On \ applying \ cross \ multiplication,we \ get\\\\2(10x-7)=3(5x+5)\\\\20x-14=15x+15\\\\On \ subtracting \ "15x" \ from \ both \ sides,we \ get\\\\20x-14-15x=5x+15-15x\\\\5x-14=15\\\\On \ adding \ "14" \ both \ sides,we \ get\\\\5x-14+14=15+14\\\\5x=29\\\\x=\frac{29}{5}
