Answer:

Step-by-step explanation:
(
)
Multiply
by each term in the parentheses.
+ 
Now, all you have to do is simplify.

X+8y=18
-5x+3y=-4
Multiply the first equation by 5
Add the two equations together
5x+40y=90
-5x+3y=-4
43y=86
Y=2
Plug y into one equation to find x
X+16=18
X=2
527,519
= 500,000 + 20,000 + 7,000 + 500 + 10 + 9
= (5) * 100,000 + (2) * 10,000 + (7) * 1,000 + (5) * 100 + (1) * 10 + (9) * 1
= (5) * 10⁵ + (2) * 10⁴ + (7) * 10³ + (5) * 10² + (1) * 10¹ + (9) * 10⁰
Answer:
No they are not, they intersect at some point.
