I'm marking answers as brainliest. When solving this system using elimination you should . 6x - 9y = 21, 3x + y = 5 Multiply the second equation by 2. Solve the second equation for y. Set the equations equal to each other. Multiply the second equation by 9.

Multiply the second equation by 9.

Step-by-step explanation:

To use the elimination method, you need to be able to add the equations and have one variable add to zero. That way you eliminate that variable.

The first equation has -9y. The second equation has y. If you multiply the second equation by 9, you will have 9y in the second equation. Then when you add equations, you will add -9y and 9y and will eliminate y.

Multiply the second equation by 9.

Step-by-step explanation:

6x - 9y = 21

-6x -2y = -10

-11y = 11

y = -1

3x - 1 = 5

3x = 6

x = 2

(2, -1)

1/3 + 1/5 = 8/15.
