You have two equations:
1. \( y = 4x - 5 \) (Equation 1)
2. \( y = 2x + 3 \) (Equation 2)
To find the point of intersection of these two lines (if they intersect), we can set the two equations equal to each other:
\[
4x - 5 = 2x + 3
\]
Now, let's solve for \( x \):
1. Subtract \( 2x \) from both sides:
\[
4x - 2x - 5 = 3
\]
This simplifies to:
\[
2x - 5 = 3
\]
2. Add 5 to both sides:
\[
2x = 8
\]
3. Divide by 2:
\[
x = 4
\]
Now that we have the value of \( x \), we can substitute it back into either of the original equations to find the corresponding \( y \). We'll use Equation 1:
\[
y = 4(4) - 5 = 16 - 5 = 11
\]
Thus, the point of intersection is:
\[
\boxed{(4, 11)}
\]
