Ravi uses the following step for solving an algebraic equation \(2x + 14 = 26\), \(2x = 26 - 14\). It is an example of :
Transposition
In the given equation, Ravi starts with \(2x + 14 = 26\) and rewrites it as \(2x = 26 - 14\).
The term 14, which was being added on the left-hand side, has been moved to the right-hand side, and its sign has changed from positive to negative.
This process of shifting a term from one side of an equation to the other side while reversing its sign is called transposition.
Hence, the given step is an example of transposition.
