Answer:
, 
Step-by-step explanation:
<h3>
I will use the elimination method.</h3>
We want to make the X's the same:


Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)

So:

Substitute y into either equation 1 or 2:
(I chose equation 1)



So:

Answer:
x=2
Step-by-step explanation:
You would first subsitute the y with 13. The you would subtract 3 from 3 and 13. Then you would have 10=5x. Then you would divide 5 by 5 and 10. You will get x = 2

Answer:
32
Step-by-step explanation:
n(G or F) = n(G) + n(F) - n(G and F)
Total will be the greatest when the intersection is empty
Largest number = 15 + 17 = 32
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
