3x - y = 13
0 - y = 13
y= -13
( 0 , -13)
so neither
Step-by-step explanation:
![x + 3y = 7 \\ 2x + 4y = 8 \\ x = 7 - 3y \\ 2(7 - 3y) + 4y = 8 \\ 14 - 6y + 4y = 8 \\ 14 - 2y = 8 \\ - 2y = - 6 \\ y = 3 \\ x = 7 - 3(3) \\ x = 7 - 9 \\ x = - 2](https://tex.z-dn.net/?f=x%20%2B%203y%20%3D%207%20%5C%5C%202x%20%2B%204y%20%3D%208%20%5C%5C%20x%20%3D%207%20-%203y%20%5C%5C%202%287%20-%203y%29%20%2B%204y%20%3D%208%20%5C%5C%2014%20-%206y%20%2B%204y%20%3D%208%20%5C%5C%2014%20-%202y%20%3D%208%20%5C%5C%20%20-%202y%20%3D%20%20-%206%20%5C%5C%20y%20%3D%203%20%5C%5C%20x%20%3D%207%20-%203%283%29%20%5C%5C%20x%20%3D%207%20-%209%20%5C%5C%20x%20%3D%20%20-%202)
Answer:
$16875
Step-by-step explanation:
Find the perimeter by adding all the lengths, which is 1875 ft.
Since 3ft = 1 yd, 1875/3 = 625 yds.
$27 per yard gives 625 * 27 = 16875.
Answer:

Cause if you think about it, it doesn't say how many Joseph has or how many cakes there are in total. So in my opinion, n + 13 = how many cakes Carol has.
Step-by-step explanation:
Putting the value of y
4x - 6 = 4(x + 1)
4x - 6 = 4x + 4
4x - 4x = 4 + 6
x = 10
Option B is the correct answer
