Answer :

Note: Thinking process be like, apply the Euclid’s axiom, if equals are added to equals, the wholes are equal, to show the given result.

We have, x+y=10 …(i)

and x=z …(ii)

According to the Euclid’s axiom, if equals are added to equals, the wholes are equal.

So, from Eqs. (i) and (ii)

x+y=z+y ….(iii)

From Eqs. (i) and (iii)

Z+Y=10

Is D the mid-point of the line segment AB?

It is given that

I.AE=CB II.DE=CD

HINT (I)-(II) gives (AE-DE) = (CB-CD) AD=DB
