Jemma wants to solve the following system using the elimination method:

y = x - 6

y = 6x - 19

What number should the equation y = x - 6 be multiplied by to eliminate x?

1

2

4

-6

To eliminate x, Jemma should multiply the equation y = x - 6 by - 6.

You will then get the equation: 6y = - 6x + 36

The two equations will be:

6y = - 6x + 36

y = 6x - 19

And you can see that if you add them, you will be able to eliminate x.

Your answer is - 6.

y = x - 6

y = 6x - 19

6y = - 6x + 36

We multiply - 6 to eliminate x.

The answer would be - 6
