What is the answer to 2x+3=4x+6-(2x+3)

I am still learning, and am most likely incorrect.

I believe you remove the 3's since their not needed, and do this:

2x = 4x + 6 - (2x)

so then just ignore "x" and do this:

2 = 4 + 6 - 2

2 = 10 - 2

2 = 8

x = 8

6mm^3 or .6cm^3

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.
