Question

5x+8y=1
-2x+8y=-6

Answer 1

So we have to solve the system?
We can do so by either employing the `Substitution method` or by `Elimination`.
Are you familiar with either of these two approaches? :)

Answer 2

YES, i tried addition elimination but it didnt work. what do i multiply by?

Answer 3

Looks like we could multiply one of the equations by (-1) and then we can ADD to cancel the `y`'s out.
