Question

if x=2 and y=-1 then the value of 2x+y​

Answer 1

Answer:

5

Step-by-step explanation:

Given x=2 and y=-1

So, 2x + y = 2 × 2 + 1 = 4 + 1 = 5

Answer 2

• 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 $3.$
