Answer 2

It seems that you have provided two linear equations in the variables x and y. To solve this system of equations, we can use either substitution or elimination method. Let's solve it using the elimination method:

Given equations:

1. 4x + y = -4
2. 8x + 4y = -8

To eliminate the variable y, we can multiply equation 1 by -4 and equation 2 by 1/4:

-4(4x + y) = -4(-4) (1/4)(8x + 4y) = (1/4)(-8)

Simplifying these equations:

-16x - 4y = 16 2x + y = -2

Now we have a new system of equations: -16x - 4y = 16 2x + y = -2

We can eliminate y by multiplying the second equation by 4 and adding it to the first equation:

-16x - 4y + 8x + 4y = 16 + (-8) -8x = 8 x = -1

Substituting the value of x into equation 2, we can solve for y:

2(-1) + y = -2 -2 + y = -2 y = 0

Therefore, the solution to the system of equations is x = -1 and y = 0.
