To solve the system of equations by inspection, let's first write the given equations clearly:
1. \( y = 35x - 5 \)
2. \( y = -35x - 5 \)
Now, we can set these two equations equal to each other since they both equal \( y \):
\[
35x - 5 = -35x - 5
\]
Next, we can add \( 35x \) to both sides:
\[
35x + 35x - 5 = -5
\]
\[
70x - 5 = -5
\]
Now, add 5 to both sides:
\[
70x = 0
\]
Dividing by 70 gives us:
\[
x = 0
\]
Now, we can substitute \( x = 0 \) back into either of the original equations to find \( y \). Let's substitute it into the first equation:
\[
y = 35(0) - 5 = -5
\]
Thus, we have found one solution to the system:
\[
(x, y) = (0, -5)
\]
To confirm, we can plug \( x = 0 \) into the second equation:
\[
y = -35(0) - 5 = -5
\]
Both equations give us the same value for \( y \), confirming that our solution is correct.
Thus, the solution to the system of equations is:
\[
\boxed{(0, -5)}
\]
1. \( y = 35x - 5 \)
2. \( y = -35x - 5 \)
Now, we can set these two equations equal to each other since they both equal \( y \):
\[
35x - 5 = -35x - 5
\]
Next, we can add \( 35x \) to both sides:
\[
35x + 35x - 5 = -5
\]
\[
70x - 5 = -5
\]
Now, add 5 to both sides:
\[
70x = 0
\]
Dividing by 70 gives us:
\[
x = 0
\]
Now, we can substitute \( x = 0 \) back into either of the original equations to find \( y \). Let's substitute it into the first equation:
\[
y = 35(0) - 5 = -5
\]
Thus, we have found one solution to the system:
\[
(x, y) = (0, -5)
\]
To confirm, we can plug \( x = 0 \) into the second equation:
\[
y = -35(0) - 5 = -5
\]
Both equations give us the same value for \( y \), confirming that our solution is correct.
Thus, the solution to the system of equations is:
\[
\boxed{(0, -5)}
