For the given equations, we will match the equation with its solution type
The first equation: x = 2
X has only one value
so, the type of the solution is: Single solution
The second equation: x = x
X will have infinite values as it is on both sides
So, the type of the solution is: Infinite solutions/All Real Number
The third equation: 3 = 3
X does not appear in the equation but the equation is true
So, the type of the solution is: Infinite solutions/All Real Number
The fourth equation: 1 = 3
X does not appear in the equation but the equation is wrong
So, the type of the solution is: No Solution/Empty Set
The fifth equation: 17 = x
X has only one value
so, the type of the solution is: Single solution
The last equation: 1 = -1
X does not appear in the equation but the equation is wrong
So, the type of the solution is: No Solution/Empty Set
