find 3 consecutive odd integers such that the sum of twice the first and three times the second is 55 more than twice the third

Let's define the three consecutive odd integers as:

- First odd integer: \( x \)
- Second odd integer: \( x + 2 \)
- Third odd integer: \( x + 4 \)

The problem states: 

- Twice the first integer: \( 2x \)
- Three times the second integer: \( 3(x + 2) \)
- Twice the third integer: \( 2(x + 4) \)

The equation provided is that the sum of twice the first and three times the second is 55 more than twice the third. Therefore, we can write:

\[
2x + 3(x + 2) = 2(x + 4) + 55
\]

Now, let's simplify and solve the equation:

\[
2x + 3x + 6 = 2x + 8 + 55
\]

Combine like terms:

\[
5x + 6 = 2x + 63
\]

Subtract \( 2x \) from both sides:

\[
3x + 6 = 63
\]

Subtract 6 from both sides:

\[
3x = 57
\]

Divide by 3:

\[
x = 19
\]

So the three consecutive odd integers are \( x = 19 \), \( x + 2 = 21 \), and \( x + 4 = 23 \).

### Verification:

- Twice the first: \( 2 \times 19 = 38 \)
- Three times the second: \( 3 \times 21 = 63 \)
- Twice the third: \( 2 \times 23 = 46 \)

Check the sum:

\[
38 + 63 = 101
\]

Check if this equals 55 more than twice the third:

\[
46 + 55 = 101
\]

Since both sides are equal, the solution is correct.

### The three consecutive odd integers are 19, 21, and 23.
