Answer:

x = -2

Step-by-step explanation:

Arrange 6x + y= -5, -6x + 12y=96 vertically:

6x + y= -5

-6x + 12y=96 Now combine like terms:

--------------------

13y = 91

Solving for y by dividing both sides by 13: y = 7

Find x by substituting 7 for y in the second equation: -6x + 12(7) = 96

Then -6x = -84 + 96, or:

-6x = 12, and so x = -2

Dovator [93]

Answer:

y = 10

Step-by-step explanation:

To find the y coordinate of the midpoint, take the y coordinates of the endpoints and average

(0+y)/2 = 5

Multiply each die by 2

0+y = 10

y = 10
