Answer:
y = -1
Explanation:
*Assuming we have to solve for Y*
Midpoint is a point that divides a line segment exactly in halve therefore making both sides of the segment equal to each other.
Now let's set these two lengths equal to each other and solve for Y:
5y +(I think you meant plus) 13 = 5 - 3Y
5y + 13 = 5 - 3y
-5 -5
5y + 8 = -3y
-5y -5y
8 = -8y
/-8 /-8
y = -1
