To find the solution to the system of equations given:
1. \( 5x + 3y = 29 \) (Equation 1)
2. \( 2x - y = 5 \) (Equation 2)
We can solve this using substitution or elimination. We'll use substitution here.
First, let's solve Equation 2 for \(y\):
\[
2x - y = 5 \implies y = 2x - 5
\]
Next, we'll substitute \(y\) in Equation 1:
\[
5x + 3(2x - 5) = 29
\]
Now, simplify the equation:
\[
5x + 6x - 15 = 29
\]
Combine like terms:
\[
11x - 15 = 29
\]
Add 15 to both sides:
\[
11x = 44
\]
Now, divide by 11:
\[
x = 4
\]
Next, substitute \(x = 4\) back into the expression for \(y\):
\[
y = 2(4) - 5 = 8 - 5 = 3
\]
Thus, the solution to the system is \((4, 3)\).
**The correct ordered pair is (4, 3).**
