3x + (2x)/2 = 60

1.5x + 2x = 120
3.5x = 120

x ≠ 12

but 

6x + 2x = 120
8x = 120
x = 15

Sorry I can't see how you'd get 12.  I must be rusty.

If e proceeded to remove the /2 only from that term and forgot the others and kept the 3x and 60, maybe?


If he only removed the /2, left the 60 unchanged and then added the 3x to the 2x he would get 12.  Probably what he did.
