15% of 11.50 = 1.72 --> 11.50 - 1.725 = 9.77
9.77 - 1.50 = 8.27/2 = 4.14
4.14 Per serving of pancakes.
Answer:
Step-by-step explanation:
![x - 10y = 18](https://tex.z-dn.net/?f=x%20-%2010y%20%3D%2018)
![-6x - 10y = 32](https://tex.z-dn.net/?f=-6x%20-%2010y%20%3D%2032)
Since both equations have
, we can subtract the second equation from the first to try and solve for
:
![(x - 10y) - (-6x - 10y) = 18 - 32](https://tex.z-dn.net/?f=%28x%20-%2010y%29%20-%20%28-6x%20-%2010y%29%20%3D%2018%20-%2032)
![x - 10y + 6x + 10y = -14](https://tex.z-dn.net/?f=x%20-%2010y%20%2B%206x%20%2B%2010y%20%3D%20-14)
![7x = -14](https://tex.z-dn.net/?f=7x%20%3D%20-14)
![x = -2](https://tex.z-dn.net/?f=x%20%3D%20-2)
With this, we can plug the value back into the first equation to solve for
:
![(-2) - 10y = 18](https://tex.z-dn.net/?f=%28-2%29%20-%2010y%20%3D%2018)
![-2 - 10y = 18](https://tex.z-dn.net/?f=-2%20-%2010y%20%3D%2018)
![-10y = 20](https://tex.z-dn.net/?f=-10y%20%3D%2020)
![y = -2](https://tex.z-dn.net/?f=y%20%3D%20-2)
Therefore, the solution is ![x = -2, y = -2](https://tex.z-dn.net/?f=x%20%3D%20-2%2C%20y%20%3D%20-2)
