4x + 3y = 54 (1)
3x + 9y = 108 (2)

Multiply (1) by (-3)
-12x - 9y = -162 
3x + 9y = 108
---------------------add
-9x  =  -54
   x = 6

plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
  y = 10

Answer
(6 , 10)

What is the length of XY
arsen [322]

Answer:

6

Step-by-step explanation:

We know that MY is the same length as XM according to definition of segment bisector. We can create an equation:

5x + 8 = 9x + 12

Minus 8 on both sides

5x = 9x + 4

-4 = 4x

x = -1

Now substitute both sides of the equation with -1 instead of x

-5 + 8 = -9x + 12

3 = 3

XY = MY + XM

XY = 3 + 3 = 6

Hope this helps :)

Have an awesome day!
