Question

x=2/3,y=-5/6z=-7/9 verify x+(y+z)=(x+y)+z for the following values of x,y and z​

Answer 1

Answer:

Given-x=2/3,y=-5/6,z= -7/9

to prove - x+(y+z)=(x+y)+z

prove.

LHS=x+(y+z)

put value of x,y,z on LHS

=2/3+(-5/6)+(-7/9)

=2/3-5/6-7/9

=12-15-14/18

=12-29/18

= -17/18

RHS =(x+y)+z

put value of x,y,x on RHS

={2/3+(-5/6)}+(-7/9)

=2/3-5/6-7/9

=12-15-14/18

= -17/18

LHS=RHS

Hence proved
