Find the value of X and Y in the parallelogram
### Directions: 
Find the value of X and Y in the parallelogram below. Show your calculations and equations.

#### Diagram:
- The shape in the diagram is a parallelogram.
- There are four angles, and two of them are labeled with expressions:
  - \( (4x - 37)^\circ \)
  - \( 49^\circ \)
  - \( 4x - 3 \)
  - \( \frac{y}{5} \)

#### Solution:

1. **Understanding the properties of a parallelogram:**
   - Opposite angles in a parallelogram are equal.
   - Adjacent angles in a parallelogram are supplementary (sum to \(180^\circ\)).

2. **Step-by-step calculations:**

   **Finding X:**

   - Consider the angles \( 4x - 3 \) and \( (4x - 37)^\circ \).
   - They must be equal because they are opposite angles in a parallelogram.

     \[
     4x - 3 = (4x - 37)
     \]

   - Solving for \( x \):

     \[
     4x - 3 = 4x - 37
     \]
     \[
     -3 = -37
     \]
     This indicates an error, as both angles \( 4x - 3 \) and \( 4x - 37 \) contradict the property of equal opposite angles.

   **Alternative Approach:**

   - Consider the angle \( (4x - 37)^\circ \) and adjacent angle \( 49^\circ \).
   - These two angles must add up to \( 180^\circ \) (supplementary angles).

     \[
     (4x - 37)^\circ + 49^\circ = 180^\circ
     \]

     \[
     4x - 37 + 49 = 180
     \]

     \[
     4x + 12 = 180
     \]

     \[
     4x = 168
     \]

     \[
     x = 42
     \]

3. **Finding Y:**

   - The angle opposite \( 49^\circ \) is \( \frac{y}{5} \).

     \[
     \frac{y}{5} = 49
