To solve the system of equations by inspection, we have the following two equations:

  1. \( y = 35x - 5 \)
  2. \( y = -35x - 5 \)

We can set these equations equal to each other because they both equal \( y \):

\[ 35x - 5 = -35x - 5 \]

Next, we'll solve for \( x \) by first adding \( 35x \) to both sides:

\[ 35x + 35x - 5 = -5 \] \[ 70x - 5 = -5 \]

Now, we can add \( 5 \) to both sides:

\[ 70x = 0 \]

Dividing both sides by \( 70 \):

\[ x = 0 \]

Now that we have the value of \( x \), we can find the corresponding value of \( y \) by substituting \( x = 0 \) into either equation. Using the first equation:

\[ y = 35(0) - 5 = -5 \]

Thus, we have the solution \( (0, -5) \).

Now, checking if this point satisfies both equations:

For the first equation:

\[ y = 35(0) - 5 = -5 \]

For the second equation:

\[ y = -35(0) - 5 = -5 \]

Both equations are satisfied by the point \( (0, -5) \).

The solution to the system of equations is:

\[ (0, -5) \]

Thus, the correct response is:

(0,−5)
