Let, the numbers = x,y
Now, x + y = 38
x - y = 50, x = 50 + y
Substitute it into first equation,
50 + y + y = 38
2y = 38 - 50
y = -12 / 2
y = -6
Substitute it into first equation,
x - 6 = 38
x = 38 + 6 = 44
So, your final answer is x = 44 & y = -6
Hope this helps!

Answer:
AB = 9
Step-by-step explanation:
Given that line, l is a perpendicular bisector of line segment AC. It intersects line segment AC at point B.
So, we can conclude that AB = BC ............ (1)
Also given that the length of line segment BC is 9.
Now, from equation (1) we can say that, AB = 9.
Therefore, the length of segment AB is 9. (Answer)
