Question

Find a pair of numbers that is a member of both x=−y+3 and x=−y−7.

Options:
A) (-5, 8)
B) (-2, 5)
C) (0, -3)
D) (4, -11)

Answer 1

There are no values of x and y that satisfy both equations.

Step-by-step explanation:

To find a pair of numbers that is a member of both equations, we need to solve the system of equations. Let's start with the given equations:

x = -y + 3

x = -y - 7

By setting the two equations equal to each other, we can solve for x and y:

-y + 3 = -y - 7

Adding y to both sides:

3 = -7

Since 3 does not equal -7, there are no values of x and y that satisfy both equations.

Therefore, none of the provided options is the correct answer.
