Explanation:

The y is a placeholder for a number. In this case, we'll replace it with 4.

So becomes

Use the order of operations PEMDAS to simplify

Therefore, evaluates to 70 when y = 4.

Put another way, the equation has one solution that is y = 4.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

10

7+3=10
