Question

x= 5/2¹ y= -3/4 find (x+y) ÷(x-y) ​

Answer 1

Answer:

$x = \frac{5}{2} \\ y = \frac{ - 3}{4} \\ \\ (x + y) \div (x - y) \\ = ( \frac{5}{2} + \frac{ - 3}{4} ) \div ( \frac{5}{2} - \frac{ - 3}{4} ) \\ = ( \frac{10 + ( - 3)}{4} ) \div ( \frac{10 - ( - 3)}{4} ) \\ = ( \frac{10 - 3}{4} ) \div ( \frac{10 + 3}{4} ) \\ = \frac{7}{4} \div \frac{13}{4} \\ = \frac{7}{ \cancel 4} \times \frac{ \cancel 4}{13} \\ \boxed{ = \underline{ \underline{ \large \frac{7}{13} }}}$
