у= -2x +5: y=-2x

You have two equations:

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

To find the solution to this system of equations, we can set them equal to each other since both represent \( y \):

\[ -2x + 5 = -2x \]

To solve for \( x \), we can add \( 2x \) to both sides:

\[ -2x + 2x + 5 = -2x + 2x \] \[ 5 = 0 \]

This equation is not true. It indicates that there is no solution to the system of equations, meaning the lines are parallel and do not intersect.

Summary:

• The two lines represented by the equations are parallel.
• They do not have any points of intersection and thus have no solution.
