Answer:


\boxed {\boxed {\sf XY= 11}}

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.


XY= YZ

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


3x+2=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.


(3x-x) +2 = (x-x)+8


2x+2=8

Subtract 2 from both sides of the equation.


2x+(2-2)= (8-2)


2x=6

Divide both sides of the equation by 2.


2x/2= 6/2


x= 6/2 \\x=3

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


XY= 3x+2 \\XY=3(3) +2\\XY=9+2 \\XY=11

Answer:

XY = 11

Explanation:

XY = YZ

3x +2 = x +8

2x = 6 . . . . . . . . . subtract x+2

x = 3

XY = 3 +8 . . . . . . . . x +8 is the same as 3x+2

XY = 11
