Answer 2

Hello Friend

Here is your answer

x = 3/4

y = - 7/2

We find out x + y/x - y

Now put the value of x and y , we get

$\frac{3}{4} + \frac{ \frac{3}{4} }{ \frac{ - 7}{2} } - ( \frac{ - 7}{2} ) \\ \\ = \frac{3}{4} + \frac{3}{4} \times ( \frac{ 2}{ - 7} ) + \frac{7}{2} \\ \\ = \frac{3}{4} - \frac{3}{14} + \frac{7}{2} \\ \\ = \frac{21 - 6 + 98}{28} \\ \\ = \frac{119 - 6}{28} \\ \\ = \frac{113}{28}$

Hope it helps you
