Question

Solve the system of equations: y = -5 and 5x + 4y = -20

What is the value of x and y, respectively?
A) x = 4, y = -5
B) x = -4, y = 5
C) x = -4, y = -5
D) x = 4, y = 5

Answer 1

C) x = -4, y = -5. To solve the given system of equations, substitute the value of y from the first equation into the second equation to find the value of x and y.

Step-by-step explanation:

To solve the given system of equations, we can substitute the value of y from the first equation into the second equation:

5x + 4(-5) = -20

5x - 20 = -20

5x = 0

x = 0/5

x = 0

Therefore, the value of x is 0 and the value of y is -5.
