To solve the system of equations using the method of elimination, we have the following equations:
1. \( 3x - 2y = 10 \) \quad (Equation 1)
2. \( 3x + 2y = 14 \) \quad (Equation 2)
**Step 1: Eliminate one variable.**
To eliminate \( y \), we will add both equations together.
\[
(3x - 2y) + (3x + 2y) = 10 + 14
\]
This simplifies to:
\[
3x - 2y + 3x + 2y = 24
\]
The \( -2y \) and \( +2y \) cancel each other out:
\[
6x = 24
\]
**Step 2: Solve for \( x \).**
Now, divide both sides by 6:
\[
x = \frac{24}{6} = 4
\]
**Step 3: Substitute \( x \) back into one of the original equations to find \( y \).**
Let's use Equation 1 for this:
\[
3(4) - 2y = 10
\]
This gives:
\[
12 - 2y = 10
\]
Now, isolate \( -2y \):
\[
-2y = 10 - 12
\]
\[
-2y = -2
\]
Now, divide by -2:
\[
y = \frac{-2}{-2} = 1
\]
**Step 4: Write the final answer as an ordered pair.**
The solution to the system of equations is:
\[
(x, y) = (4, 1)
\]
Thus, the final answer is \((4, 1)\).
1. \( 3x - 2y = 10 \) \quad (Equation 1)
2. \( 3x + 2y = 14 \) \quad (Equation 2)
**Step 1: Eliminate one variable.**
