Answer 1

Answer:

(x,y) = (1/3,-1)

Step-by-step explanation:

Given,    $\frac{4}{x}+5y=7$    and    $\frac{3}{x}+4y =5$

        =>  $\frac{12}{x}+15y=21$     and     $\frac{12}{x}+16y=20$  

        =>  $\frac{12}{x}+15y=21$     and     $-\frac{12}{x}- 16y =-20$

By adding both, we get  

        =>  $-y =1$  =>  y = -1

putting y = -1 in  $\frac{4}{x}+5y=7$  , we get

        =>  $\frac{4}{x}-5 =7$    =>   x = 1/3
