Question

find (x+y)÷(x-y) if x=1/4,y=3/2​

Answer 1

x=1/4,y=3/2

$\frac{x + y}{x - y} \\ \\ = \frac{ \frac{1}{4} + \frac{3}{2} }{ \frac{1}{4} - \frac{3}{2} } \\ \\ = \frac{ (\frac{1}{4} + \frac{6}{4} )}{ (\frac{1}{4} - \frac{6}{4}) } \\ \\ = \frac{( \frac{1 + 6}{4}) }{( \frac{1 - 6}{4} )} \\ \\ = \frac{ \frac{7}{4} }{ \frac{ - 5}{4} } \\ \\ = \frac{ - 7}{5}$
