Answer:
Multiply each term in the second equation by 2
Step-by-step explanation:
We have a system of equations that are wanted to be solve through elimination, which would be adding/subtracting the two systems of equations together and finding a variable. Knowing that, we need to find a way to cancel out one of the variables in the system of equation, which in this case is the lower value, y. So looking at both equations, we see we have -2y and y, to get y to 2y, we would need to multiply it by 2. But we can't leave that alone, we would have to multiply each term in the second equation by 2. Therefore giving us the answer.
