Given that,
AB + BC = 24 and AB = 10, then 10 + BC = 24.
To find,
The above expression is an example of what?
Solution,
We have,
AB + BC = 24 ....(1)
and
AB = 10
Substitute AB = 10 in equation (1).
10+BC=24
BC = 24-10
BC = 14
Therefore, we have used Substitution Property. Hence, the correct option is (2).
