4y = -23 + 39
4y = 16
y = 4
Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9
x = -9
y = 4
104 divided by 12 is 8.6666666667
So if you round up it would be 9 but technically he could only get 8 fence posts from 104 inches of lumber if he needed 12 inches for each fence post.
The answer is 8 fence posts.
