The value of x/y = -8/9.

Step-by-step explanation:

In the question there is some mistake, the correct equation can be described as follows:

$\ Given \ value:\\\\\frac{3x-5y}{7x-4y} = \frac{3}{4} \\\\\ find:\\\\\frac{x}{y} =?\\\\\ Solution:\\\\\frac{3x-5y}{7x-4y} = \frac{3}{4} \\\\\rightarrow (3x-5y) \times 4 = (7x-4y) \times 3 \\\\\rightarrow 12x- 20y= 21x-12y\\\\\rightarrow 21x-12x -12y+20y=0\\\\\rightarrow 9x +8y=0\\\\\rightarrow 9x = -8y\\\\\rightarrow \frac{x}{y}= \frac{-8}{9}$
