12+4n/3 = 8
4n/3 = -4
4n = -12
n = -3

Sub your answer and mine back into the original problem. Which one works?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

9a - 3(a -6) = -6
9a - 3a + 18 = -6

Take it from there.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If the width is 6, the length must be 12.

P = 2L + 2W
68 = 24 + 12

Nope! That doesn't work. Try again.

Combine like terms and solve for a.


56 is not the width.
