  • As per the data given in the question, we have to find the value of the expression.

             Given data:-x=2   \ y=-1.  

             To find:- The value of the expression.

             Solution:-

  • We know that addition means adding two or more than two numbers together.
  • The addition is denoted by (+).
  • properties of addition are as follows,
  1. Identity Property of Zero.
  2. Inverse Property.
  3. Commutative Property.
  4. Associative Property.

 Therefore putting the value of x and y we get,

             2x+y\\=2(2)+(-1)\\=4-1\\=3.

Hence we will get the value 3.
