not so sure about this one either.
(anything typed such as 7/6 are fractions, not sure how to type it.
x+7/6=2x7/6
6(x+7/6)=6(2x7/6)
6x+7=12x7
6x 6x
7=6x7
+7 +7
6x/6= 14/6

x = 14/6 = 7/3 is the correct answer.
Your error was made in the last step. You should have come up with 6x = 14

x+7/6=2x7/6
6(x+7/6)=6(2x7/6)
6x+7=12x7
Subtract 6x from both sides and add 7 to both sides.
6x = 14
x = 14/6 = 7/3 = 2 1/3
I hope this helps a little more. Thanks for asking.
