Answer:
D. Multiply the second equation by 3. The solution is x = 12, y = 10.
Step-by-step explanation:
First, look at the y variable of the first equation. It is 3y.
To solve by elimination, the variables have to add together to 0.
So, -3y needs to be added to -3y to eliminate the y variable.
The second equation has the y variable of -y, so it has to be multiplied by 3.
So, answer choice D is the correct answer.
