Answer 1

Step-by-step explanation:

here's the answer friend

Answer 2

$\frac{10}{x + y} + \frac{2}{x - y} = 4 \: \: \:$

$\frac{15}{x + y} - \frac{5}{x - y} = - 2$

$let \frac{1}{x + y} = u \: and \: \frac{1}{x - y} = v$

$10u + 2v = 4 \: \: \: \: \: \: 15u - 5v = - 2$

Eliminating u

30u+6v=12

-30u±10v=±4

___________

16v=16

___________

v=1

10u+2(1)=4

u=1/5

$\frac{1}{x + y} = \frac{1}{5} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \frac{1}{x - y} = 1$

Reciprocaling both sides

x+y=5. x-y=1

Eliminating y

x+y=5

x-y=1

______

2x=6

_______

x=3

x-y=1

3-y=1

-y=-2

y=2
