Question

"What is the y value to this system of equations: x= -y -5, 4x + 7y= -44.

A) -20
B) 10
C) -10
D) 20"

Answer 1

The y value in the system of equations is -8.

Step-by-step explanation:

To find the y value in this system of equations, we can substitute the value of x from the first equation into the second equation.

First, substitute x=-y-5 in the second equation:

4(-y-5) + 7y = -44

-4y - 20 + 7y = -44

Combine like terms:

3y - 20 = -44

Add 20 to both sides:

3y = -24

Divide by 3:

y = -8

So, the y value of this system of equations is -8.
