Answer 2

Step-by-step explanation:

Given,

x = 1/2 , y = 2/3 , z = -1/5

Now, LHS :-

$=(x + y) + z$

substituting given values

$= ( \frac{1}{2} + \frac{2}{3} ) + \frac{ - 1}{5}$

$= by \: taking \: lcm \\ (\frac{3 + 4}{6}) - \frac{1}{5}$

$= ( \frac{7}{6} ) - \frac{1}{5} \\ = ( \frac{35 - 6}{30} ) \\ = \frac{29}{30}$

Now, RHS:-

$= x + (y + z)$

$= \frac{1}{2} + ( \frac{2}{3} + \frac{ - 1}{5} )$

$= \frac{1}{2} + ( \frac{10 - 3}{15} )$

$= \frac{1}{2} + ( \frac{7}{15} )$

$= \frac{15 + 14}{30}$

$= \frac{29}{30}$

LHS =RHS

Hence verified.
