Question

solve x - 10 = 15 , state the axiom used here

Answer 1

Given,

x-10=15.

We can add 10 on both the sides to find the required value of x.

So,

x-10+10=15+10.
x=25.

Therefore, we found the value of x to be 25 by using the axiom : when equals are added to equals the wholes are equal.

Answer 2

x-10 = 15
= by adding both side 10
= x-10+10 = 15+10
= x= 25

axiom = things which are added to the same thing are equal to one another
