Does BC=CD? If so,

3x+2=5x-10

12=2x

12/2=x

if BC=DC then you would do

3x+2=5x-10

then you do algebra by adding 10 to both sides like this

3x+2=5x-10

+10 +10 the 10s cancel out

------------

3x+2=5x

then you subtract 3x from both sides like soo

3x+12=5x

-3x -3x 3Xs cancel out

-----------

12=2x then you divide 2 from both sides

/2 /2

answer: 6=X
