I think you just need to prove it

Lets say that the equation is

10x - 6   = 4x + 12

from this, we know that 

6x   =  18
x = 3

If you put 3 and substitute it to x, you can get the same result

hope this helps

The linear function is: g = 3n-2. Plug in values from -2 to 4 into n. Like so, G = 3(-2)-2 = g = -8. So, n(x) = -2 and g(y) = -8. And so on, and so on.

Basically, your n values are the x values.
The number you get out of the equation will be your y value.
