Answer :

Steps:
1. Substitute the y in y=4x + 4 and put
X-6=-4x+4
2. Add 4x to both sides
3. 5x-6=4
4. Add 6 to both sides
5. 5x=10
6. Divide by 5 on both sides
7. X=2
8. Now to find the y, you substitute 2 for x in the problem y=x-6
9. Y=2-6
10. Y=-4
11. Your answer is
(2, -4)
x=y+6 add 6 to the other side

y=-4(y+6)+4 substitute x with y+6

y=-4y-24+4 Simplify

5y=-20 add 4y to both sides and add like pairs

y=-20/5=-4      y=-4

-4=x-6 substitute y with -4 in second equation to find x

2=x add 6 to both sides

(2,-4)
