To solve the system of equations:
1. \( 5x + 2y = 14 \) (Equation 1)
2. \( x - 6y = 22 \) (Equation 2)
We can solve it using substitution or elimination. Here, we will use substitution.
First, let’s solve Equation 2 for \( x \):
\[
x = 6y + 22
\]
Now we can substitute \( x \) in Equation 1:
\[
5(6y + 22) + 2y = 14
\]
Expanding this gives us:
\[
30y + 110 + 2y = 14
\]
Combine like terms:
\[
32y + 110 = 14
\]
Subtract 110 from both sides:
\[
32y = 14 - 110
\]
\[
32y = -96
\]
Now, divide by 32:
\[
y = \frac{-96}{32} = -3
\]
Now we know \( y \), we can substitute \( y \) back into the equation for \( x \):
\[
x = 6(-3) + 22
\]
\[
x = -18 + 22
\]
\[
x = 4
\]
Thus, the solution to the system of equations is:
\[
(x, y) = (4, -3)
\]
So the final answer is:
\((4, -3)\)
