BE = 3x - 1
BC = BD - CD = 2x - 4 - 2
DE = CE - CD = 2x - 3 - 2
_______________________
BC + CD + DE = BE
( 2x - 4 - 2 ) + 2 + ( 2x - 3 - 2 ) = 3x - 1
2x - 6 + 2 + 2x - 5 = 3x - 1
2x + 2x - 5 - 6 + 2 = 3x - 1
4x - 11 + 2 = 3x - 1
4x - 9 = 3x - 1
Add both sides 9
4x - 9 + 9 = 3x - 1 + 9
4x = 3x + 8
Subtract both sides 3x
4x - 3x = 3x - 3x + 8
<em>x = 8 </em>
___________________
BD = 2x - 4
BD = 2(<em>8</em><em> </em>) - 4
BD = 16 - 4
BD = 12
And we're done...
