x=4

Explanation:

First, use distributive property on the (12)(4+6x) and (23)(x+9).

(12)(4+6x)=(12)4+(12)6x=2+3x
(23)(x+9)=(23)x+(23)9=23x+6

The equation is now 2+3x=13x+23x+6.

Combine like terms and make it "prettier".

3x2=x+6.

Now we've broken it down into something much more simple!

Subtract 6 from both sides to get
3x26=x+663x8=x

Subtract x from both sides to get
3xx8=xx2x8=0

Add 8 to both sides to get
2x8+8=0+82x=8

Final step: Divide 2 from both sides to get
2x2=82x=4

Therefore, x=4.

Yay!
