To solve the system of equations using the elimination method, we start with the two equations:

  1. \( 2x - 3y = 14 \) (Equation 1)
  2. \( 4x + 3y = 10 \) (Equation 2)

Step 1: Align the equations

\[ \begin{align*} (1) & \quad 2x - 3y = 14 \ (2) & \quad 4x + 3y = 10 \ \end{align*} \]

Step 2: Eliminate \(y\)

To eliminate \(y\), we can add the two equations directly, but first, we need to make the coefficients of \(y\) equal. In this case, we can multiply Equation 1 by 1 (keeping it the same) and Equation 2 by 1 (also keeping it the same) since \(3y\) in Equation 2 and \(-3y\) in Equation 1 are already opposites.

Now, we add the two equations:

\[ (2x - 3y) + (4x + 3y) = 14 + 10 \]

This simplifies to:

\[ 2x + 4x - 3y + 3y = 24 \]

Which results in:

\[ 6x = 24 \]

Step 3: Solve for \(x\)

Now we can divide both sides by 6:

\[ x = \frac{24}{6} = 4 \]

Step 4: Substitute \(x\) back into one of the original equations

Now that we have \(x = 4\), we can substitute it back into either original equation to find \(y\). Let's use Equation 1:

\[ 2(4) - 3y = 14 \]

This simplifies to:

\[ 8 - 3y = 14 \]

Step 5: Solve for \(y\)

Subtract 8 from both sides:

\[ -3y = 14 - 8 \] \[ -3y = 6 \]

Now divide both sides by -3:

\[ y = \frac{6}{-3} = -2 \]

Conclusion

The solution to the system of equations is:

\[ (x, y) = (4, -2) \]

Thus, the final answer is:

\[ \boxed{(4, -2)} \]
