## Thinking Mathematically (6th Edition)

The solution set of an equation contains the number of solutions of that particular equation. For example: Consider the equation. ${{x}^{2}}=x+x$ Here, the number that satisfies the above equation is called the solution of the equation. The set formed containing those solutions is called solution set of an equation. The above equation has 0, 2 as the solution that means it satisfies the equation. The solution set of this assumed equation is represented as$\left\{ 0,2 \right\}$.
