We know the sum of the angles of a quadrilateral is 360 degrees. We know a linear pair is 180 degrees. Find x and y, (10y-6), (7x), (3x), and on the exterior (4x+27)

We are given a quadrilateral where the angles include expressions involving \(x\) and \(y\). The problem also mentions an exterior angle (associated with one of the interior angles). Let's break it down step by step.

### Step 1: Understand the information provided
- The sum of the interior angles of a quadrilateral is 360 degrees.
- There are four angles:
  - \(10y - 6\)
  - \(7x\)
  - \(3x\)
  - One exterior angle \(4x + 27\).

### Step 2: Use the property of a linear pair
The exterior angle given is \(4x + 27\). The interior angle corresponding to this exterior angle is part of the quadrilateral, and the interior angle and exterior angle form a linear pair. Thus, the sum of these two angles must be 180 degrees.

Let the interior angle opposite the exterior angle \(4x + 27\) be represented as \(A\). Since \(A + (4x + 27) = 180^\circ\), we can solve for \(A\):
\[
A = 180 - (4x + 27) = 180 - 4x - 27 = 153 - 4x.
\]

### Step 3: Write the equation for the sum of the interior angles
The sum of the interior angles in a quadrilateral is 360 degrees. The interior angles are:
- \(10y - 6\)
- \(7x\)
- \(3x\)
- \(153 - 4x\)

So, the equation becomes:
\[
(10y - 6) + (7x) + (3x) + (153 - 4x) = 360.
\]

### Step 4: Simplify and solve the equation
First, combine like terms:
\[
10y - 6 + (7x + 3x - 4x) + 153 = 360.
\]
\[
10y - 6 + 6x + 153 = 360.
\]
\[
10y + 6x + 147 = 360.
\]

Now, subtract 147 from both sides:
\[
10y + 6x = 213.
\]

### Step 5: Solve for \(x\) and \(y\)
This equation has two variables, so we need more information to solve it. Unfortunately, the problem does not provide additional conditions or relationships between \(x\) and \(y\). 

We can say:
\[
10y + 6x = 213.
\]
This is as far as we can simplify without more information.

### Recap of the solution:
- The sum of the interior angles gives us the equation: \(10y + 6x = 213\).
- The relationship between \(x\) and \(y\) cannot be determined from the given information, so you would need either an additional equation or a specific value for one of the variables to solve the system.
