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.
12+4n/3 = 8
Not multiple choice.. trying to find n. My answer is 7
9a - 3(a -6) = -6
Not multiple choice.. I'm not quite sure how to do this
