Step 1
We have to Evaluate

2 x + y

, Where

x = 2

y = - 5

Put , these values of x & y
So ,
Step 2

2 x + y = 2 (2) + (- 5)

= 4 - 5 = - 1

Hence ,

Step 1
We are going to substitute the values of our variables to the expression. After that we will perform operations involve to solve the given expression.
Step 2
Substitute 2 for x and 5 for y.

2 x + y \Rightarrow 2 (2) - 5

Substitute

x = 2

and

y = - 5

Step 3
Let us perform operations in our resulting expression to find the its value.

2 (2) - 5 \Rightarrow 4 - 5

Multiply 2 and 4

\Rightarrow - 1

Add
Step 4
Therefore the value of

2 x + y

is -1 when

x = 2

and

y = 5
