Answer:

(-5/2 , 3/2)

Step-by-step explanation:

y=4+x

6(4+x) + 2x= 4

24 + 6x + 2x= 4

24 + 8x= 4

8x =4 - 24

8x=-20

x= -20/8= -5/2

y-(-5/2)=4

y+5/2= 4

multiply throughout by 2 to clear out fraction

2y + 5= 8

2y= 8-5

2y=3

y=3/2

The rides she wants to ride cost 4+6+3 tickets so that goes on one side. She already has 7 tickets so you need to know 7 plus what will get her on those rides so those go on the other side. So you have:

Then you solve for t
7+t=13
t=13-7=6

Hope that helps.

-38 → -13 → <u>-9 → -2</u> → 14 → 28

Since there are 2 values, find the average of those 2 values:
