B is the midpoint of segment AC. if BC=2x-15 and AC=x+9, find x
----------------
Draw the picture: A......B......C
Mark the segments: AC = x+9 ; BC = 2x-15
-------------------------
EQUATION:
BC is (1/2)AC
2x-15 = (1/2)(x+9)
4x-30 = x+9
3x = 39
x = 13
==========

2(2X-15)=X+9
4X-30=X+9
4X-X=9+30
3X=39
X=39/3
X=13 ANSWER.
