Answer:
2
Step-by-step explanation:
We take the equation

and substitute the values for each individual variable in the problem. It looks like this:

Now we can solve the equation.
When solved, it equals 2.
If you graph the two equations then you will find that they intersect at (-2,-2).
You then have to check your answer.
x=4y+6
(-2)=4(-2)+6
-2=-8+6
-2=-2
x-3y=4
(-2)-3(-2)=4
-2+6=4
4=4
