Question

verify (x+y)+z=x+(y+z)
x=-7/11,y=2/-5,z=-3/22​

Answer 1

Answer:

Y=2/-5 =-2/5

L. H.S = {(-7/11)+(-2/5)}+(-3/22)

={-35-22/55}+(-3/22)

=-57/55 +(-3/22)

=-114-15/110

=-129/110

R.H.S = (-7/11)+{(-2/5)+(-3/22)}

= (-7/11)+{-44-15/110}

= (-7/11)-59/110

= -70-59/110

=-129/110

Here, L. H.S=R.H.S that is verify.
