Question

7. If x =-4/7 , y = 2/5,and z =2/5,

then verify that

x - y ₩ y-x​

Answer 1

Answer:

x=4/7

y=2/5x-y=y-x

=4/7-2/5=2/5(-4/7)

-20-15=2/5+4/7

ans 35=5=7

-20-14=14+20

35. 35 cancle all

-34+34

Answer 2

Answer:

x-y

$x - y = \frac{ - 4}{7} - \frac{2}{5}$

$x - y = \frac{ - 34}{35}$

y-x

$y - x = \frac{2}{5} + \frac{4}{7}$

$y - x = \frac{34}{35}$

$y - x \: \: \: \: not \: equals \: \: \: x - y$
