Answer:
<h2>x = 6 and y = 2 → (6, 2)</h2>
Step-by-step explanation:
![\left\{\begin{array}{ccc}x=3y&\text{subtract}\ 3y\ \text{from both sides}\\3x-2y=14\end{array}\right\\\\\left\{\begin{array}{ccc}x-3y=0&\text{multiply both sides by (-3)}\\3x-2y=14\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-3x+9y=0\\3x-2y=14\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad7y=14\qquad\text{divide both sides by 7}\\.\qquad\qquad y=2\\\\\text{put the value of y to the first equation:}\\x=3(2)=6](https://tex.z-dn.net/?f=%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bccc%7Dx%3D3y%26%5Ctext%7Bsubtract%7D%5C%203y%5C%20%5Ctext%7Bfrom%20both%20sides%7D%5C%5C3x-2y%3D14%5Cend%7Barray%7D%5Cright%5C%5C%5C%5C%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bccc%7Dx-3y%3D0%26%5Ctext%7Bmultiply%20both%20sides%20by%20%28-3%29%7D%5C%5C3x-2y%3D14%5Cend%7Barray%7D%5Cright%5C%5C%5Cunderline%7B%2B%5Cleft%5C%7B%5Cbegin%7Barray%7D%7Bccc%7D-3x%2B9y%3D0%5C%5C3x-2y%3D14%5Cend%7Barray%7D%5Cright%7D%5Cqquad%5Ctext%7Badd%20both%20sides%20of%20the%20equations%7D%5C%5C.%5Cqquad%5Cqquad7y%3D14%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%207%7D%5C%5C.%5Cqquad%5Cqquad%20y%3D2%5C%5C%5C%5C%5Ctext%7Bput%20the%20value%20of%20y%20to%20the%20first%20equation%3A%7D%5C%5Cx%3D3%282%29%3D6)
$8.75 per scarf
26.25/3
= 8.75
know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8
