Equivalent systems of equations review
Step-by-step explanation:
We're given two systems of equations and asked if they're equivalent.
x + 4y = 8 (1)
4x + y = 2 (2)
Interestingly, if we sum the equations in System A, we get:
![x + 4y = 8 \\4x + y = 2 \\](https://tex.z-dn.net/?f=x%20%2B%204y%20%3D%208%20%5C%5C4x%20%2B%20y%20%3D%202%20%5C%5C)
![5x+5y=10](https://tex.z-dn.net/?f=5x%2B5y%3D10)
Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:
![5x+5y=10](https://tex.z-dn.net/?f=5x%2B5y%3D10)
![4x + y = 2](https://tex.z-dn.net/?f=4x%20%2B%20y%20%3D%202)
This is System B, which means that System A is equivalent to System B.
Quotient would be 8 because 88 divided by 11 is 8.
hope this helped :D
