Answer:

C  multiply the first equation by 3

Step-by-step explanation:

3x-y =5

2x+3y = 10

We want to eliminate y

Since the first equation has a negative 1y  and the second equation has 3y

I would multiply the first equation by 3  and then the y's cancel

3(3x-y =5)

9x -3y = 15

2x+3y = 10

------------------

11x = 25
