Alright before we can bring all the a's to one side, you have to distribute the brackets, what is \[4(a+3)\]distributed?

Answer 2

4a+12

Answer 3

Yes

Answer 4

Correct!

Answer 5

Exactly so now we have \[4a+12=12+4a\]What do you think is up next?

Answer 6

comb like terms?

Answer 7

*combine

Answer 8

Yep, something weird happens when you try to do that though, right?

Answer 9

Let's combine like terms, how do you bring the 4a to one side?

Answer 10

subtract right

Answer 11

Yes, so we have \[4a-4a+12=12+4a-4a\], and the 4a's cancel! So do the 12's! there is no solution.
