Question

if x= 4/9,y=-7/12and z=-2/3, then verify that x-(y-z) ≠(x-y)-z​

Answer 1

Thank you.

if x= 4/9,y=-7/12and z=-2/3, then verify that x-(y-z) ≠(x-y)-z

Answer 2

Step-by-step explanation:

Verify:-

$x - ( y - z) \: not \: equal \: to \: (x - y) - z$

$\frac{4}{9} - ( \frac{7}{12} - \frac{2}{3} )$

$\frac{4}{9} - ( \frac{7 - 8}{12} )$

$\frac{4}{9} - ( \frac{ - 1}{12} )$

$\frac{4}{9} + \frac{1}{12}$

$\frac{16 + 3}{36}$

$\frac{19}{36}$

$( \frac{4}{9} - \frac{7}{12} ) - \frac{2}{3}$

$(\frac{16 - 21}{36} ) - \frac{2}{3}$

$\frac{ - 5}{36} - \frac{2}{3}$

$\frac{ - 5 - 24}{36}$

$\frac{ - 29}{36}$

$hence \: verified$

$thank$
