Answer:

Explanation:
We are asked to find the value of XY.
We know that Y is the midpoint of XZ. The midpoint of a line bisects the line or divides it into 2 equal parts. The point Y divides the line XZ into 2 parts : XY and YZ. Since Y is the midpoint, XY and YZ are equal.

We know that XY is equal to 3x+2 and YZ is equal to x+8.

Now we can solve for x by isolating the variable. Move all the terms with variables to one side and the constants to the other side. Subtract x from both sides of the equation.


Subtract 2 from both sides of the equation.


Divide both sides of the equation by 2.


Now we know that x is equal to 3 and we can substitute it back into 3x+2 to solve for XY.
