Question

Solve using elimination 2x+8y =8
And 2x-4y=-16

Answer 1

To solve using the elimination method, we'll need to eliminate one of the variables by adding or subtracting the two equations.

Let's add the two equations together:

(2x + 8y) + (2x - 4y) = 8 + (-16)
4x + 4y = -8

Now we need to divide the entire equation by 4 to simplify it:

x + y = -2

So the solution to the system of equations is x + y = -2.
