Answer:
(x, y) = (3, 5/2)
Step-by-step explanation:
![4x+2y=17\\3x+2y=14](https://tex.z-dn.net/?f=4x%2B2y%3D17%5C%5C3x%2B2y%3D14)
I'll solve by elimination here. If you invert the second equation and add it to the first, 2y and -2y would cancel out.
![4x+2y=17\\-(3x+2y=14)](https://tex.z-dn.net/?f=4x%2B2y%3D17%5C%5C-%283x%2B2y%3D14%29)
Now just add those from top to bottom.
![\rightarrow (4x-3x)+(2y-2y)=17-14\\\rightarrow x=3](https://tex.z-dn.net/?f=%5Crightarrow%20%284x-3x%29%2B%282y-2y%29%3D17-14%5C%5C%5Crightarrow%20x%3D3)
Nothing else needs to be done for that part. Now, you can pick either equation and use the known value of x to solve for y.
![4x+2y=17\\\rightarrow 4(3)+2y=17\\\rightarrow 12+2y=17\\\rightarrow 2y=5\\\rightarrow y=\frac{5}{2}](https://tex.z-dn.net/?f=4x%2B2y%3D17%5C%5C%5Crightarrow%204%283%29%2B2y%3D17%5C%5C%5Crightarrow%2012%2B2y%3D17%5C%5C%5Crightarrow%202y%3D5%5C%5C%5Crightarrow%20y%3D%5Cfrac%7B5%7D%7B2%7D)
(x, y) = (3, 5/2)
