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
