To solve the system of equations using the elimination method, we start with the two equations:
1) \( 2x - 3y = 14 \)
2) \( 4x + 3y = 10 \)
We can eliminate \( y \) by adding the two equations after adjusting them, or we can multiply the first equation by a suitable number to make the coefficients of \( y \) in both equations add to zero.
To eliminate \( y \), we can multiply the first equation by 1 and the second equation by 1 (since the coefficient of \( y \) in the second equation is already suitable):
1) \( 2x - 3y = 14 \)
2) \( 4x + 3y = 10 \)
Now add the two equations together:
\[
(2x - 3y) + (4x + 3y) = 14 + 10
\]
This simplifies to:
\[
6x = 24
\]
Now, solve for \( x \):
\[
x = \frac{24}{6} = 4
\]
Next, substitute \( x = 4 \) back into one of the original equations to solve for \( y \). We'll use the first equation:
\[
2(4) - 3y = 14
\]
This simplifies to:
\[
8 - 3y = 14
\]
Now, subtract 8 from both sides:
\[
-3y = 14 - 8
\]
\[
-3y = 6
\]
Now, divide by -3:
\[
y = \frac{6}{-3} = -2
\]
Thus, the solution to the system of equations is:
\[
(x, y) = (4, -2)
\]
In conclusion, the answer is:
\[
\boxed{(4, -2)}
\]
