If x=2 and y=5 find the values of :
`2x+3y`

Options

A. 18
B. 19
C. 20
D. 21

Answer

To find the value of \( 2x + 3y \) given that \( x = 2 \) and \( y = 5 \), we can follow these steps:

### Step 1: Substitute the values of \( x \) and \( y \)
We know:
- \( x = 2 \)
- \( y = 5 \)

Now, we substitute these values into the expression \( 2x + 3y \):
\[ 2x + 3y = 2(2) + 3(5) \]

### Step 2: Calculate \( 2(2) \)
Now, calculate \( 2(2) \):
\[ 2(2) = 4 \]

### Step 3: Calculate \( 3(5) \)
Next, calculate \( 3(5) \):
\[ 3(5) = 15 \]

### Step 4: Add the results from Step 2 and Step 3
Now, we add the results from the previous steps:
\[ 4 + 15 = 19 \]

### Final Answer
Thus, the value of \( 2x + 3y \) is:
\[ \boxed{19} \]
