Hope this helps! :)
X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter
So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10
If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base
You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.

Answer:
y = 5 -x
6x +3(5 -x) = 27
Step-by-step explanation:
The first equation is conveniently solved for either x or y. If we solve it for y, we get ...
y = 5 - x . . . . . . subtract x from both sides
This expression for y can be substituted into the second equation to give ...
6x +3(5 -x) = 27
These are your new system of equations.
Simplified, they are ...
_____
The second is a 2-step equation that gives the value of x, which can then be used in the first equation to find y.
3x = 12 . . . . subtract 15
x = 4 . . . . . . divide by 3
y = 5 -4 = 1 . . . . substitute into the first equation
The solution is (x, y) = (4, 1).
