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

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

First, we can eliminate \(y\) by adding the two equations together. To do this, we can multiply Equation 1 by 1 (no change necessary) and Equation 2 by 1 (again, no change):

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

Now, we add the two equations:

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

This simplifies to:

\[ 6x = 24 \]

Next, we solve for \(x\):

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

Now that we have \(x\), we will substitute this value back into one of the original equations to solve for \(y\). We'll use Equation 1:

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

This simplifies to:

\[ 8 - 3y = 14 \]

Now, we can isolate \(y\):

\[ -3y = 14 - 8 \] \[ -3y = 6 \] \[ y = \frac{6}{-3} = -2 \]

Thus, the solution to the system of equations is:

\[ x = 4, \quad y = -2 \]

Final answer:

\((4, -2)\)
