C) six times log base two of x times seven times log base two of y minus log base two of eight.
1)
x + 2y = 21
+ -x + 3y = 29
--------------------------
5y = 50
y = 10
x + 2(10) =21
x = 1
2)
6x + 6y = 30
+ 15x - 6y = 12
-------------------------------
21x = 42
x = 2
6(2) + 6y = 30
6y = 18
y = 3
24 foot board... I added a picture for the break down
Y= 4x
I think that’s the answer
