Answer:
Mirandah added 5x and 9y, which she shouldn't do because one is y and the other is x, meaning they don't match.
There is no simplifying the equation. It should stay 5x + 9y - 4

Answer:
I dont really know how to do this, but I think you have to multiply
Step-by-step explanation:
Answer:
Multiply the second equation by 2
Step-by-step explanation:
Given


Required
Get matching coefficient for elimination


The coefficient of x in both expressions are factors.
So, we can multiply the second equation by 2 to get the coefficient of x in the first.
i.e.


So, the system becomes:


<em>Now, x can be eliminated</em>
