PERFECT SQUARE
Answer:
x = 5, y = 2
Step-by-step explanation:
First, isolate y in the top equation.
![y = -5.3x+28.5](https://tex.z-dn.net/?f=y%20%3D%20-5.3x%2B28.5)
Next, substitute y in the bottom equation.
![4.2x + 3.1(-5.3x + 28.5) = 27.2](https://tex.z-dn.net/?f=4.2x%20%2B%203.1%28-5.3x%20%2B%2028.5%29%20%3D%2027.2)
![5.3x + y = 28.5](https://tex.z-dn.net/?f=5.3x%20%2B%20y%20%3D%2028.5)
Simplify.
![4.2x + -16.43x + 88.35 = 27.2](https://tex.z-dn.net/?f=4.2x%20%2B%20-16.43x%20%2B%2088.35%20%3D%2027.2)
Combine like terms.
![-12.23x + 88.35 = 27.2](https://tex.z-dn.net/?f=-12.23x%20%2B%2088.35%20%3D%2027.2)
Isolate x on one side.
![-12.23x = -61.15](https://tex.z-dn.net/?f=-12.23x%20%3D%20-61.15)
Isolate x.
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Substitute x into ![5.3x + y = 28.5](https://tex.z-dn.net/?f=5.3x%20%2B%20y%20%3D%2028.5)
![5.3(5) + y = 28.5](https://tex.z-dn.net/?f=5.3%285%29%20%2B%20y%20%3D%2028.5)
Simplify.
![26.5 + y = 28.5](https://tex.z-dn.net/?f=26.5%20%2B%20y%20%3D%2028.5)
Isolate y.
![y = 2](https://tex.z-dn.net/?f=y%20%3D%202)
![x = 5 \\y = 2](https://tex.z-dn.net/?f=x%20%3D%205%20%5C%5Cy%20%3D%202)
