There are 1760 yards in a mile. Half that distance is 880 yards.
![- 5x+2y=9 \\ y=7x](https://tex.z-dn.net/?f=%20-%205x%2B2y%3D9%20%5C%5C%20%3C%2Fp%3E%3Cp%3Ey%3D7x)
We know that y=7x, so we just need tu put it into the 1st equation
![- 5x + 2 \times 7x = 9 \\ - 5x + 14x = 9 \\ 9x = 9 | \div 9 \\ 9x \div 9 = 9 \div 9 \\ x = 1](https://tex.z-dn.net/?f=%20-%205x%20%2B%202%20%5Ctimes%207x%20%3D%209%20%5C%5C%20%20-%205x%20%2B%2014x%20%3D%209%20%5C%5C%209x%20%3D%209%20%7C%20%5Cdiv%209%20%5C%5C%209x%20%5Cdiv%209%20%3D%209%20%5Cdiv%209%20%5C%5C%20x%20%3D%201)
So we found x. Now we can find y
![y = 7 \times 1 \\ y = 7](https://tex.z-dn.net/?f=y%20%3D%207%20%5Ctimes%201%20%5C%5C%20y%20%3D%207)
Answer:
x=1, y=7; or (1;7)
