Answer:
x=5.24-9+180n,174.75+180n
Step-by-step explanation:
![x-5y=-4x-2y](https://tex.z-dn.net/?f=x-5y%3D-4x-2y)
In order to evaluate the given function at x = -3, simply replace "x" in the function with -3 and solve.
![-3-5y=-4(-3)-2y](https://tex.z-dn.net/?f=-3-5y%3D-4%28-3%29-2y)
<em>Multiply -4 and -3 in the function above.</em>
![-3-5y=12-2y](https://tex.z-dn.net/?f=-3-5y%3D12-2y)
<em>Add 3 on both sides of the equation.</em>
![-3-5y+3=12-2y+3](https://tex.z-dn.net/?f=-3-5y%2B3%3D12-2y%2B3)
![-5y=15-2y](https://tex.z-dn.net/?f=-5y%3D15-2y)
<em>Add 2y on both sides of the equation.</em>
![-5y+2y=15-2y+2y](https://tex.z-dn.net/?f=-5y%2B2y%3D15-2y%2B2y)
![-3y=15](https://tex.z-dn.net/?f=-3y%3D15)
<em>Divide both sides of the equation by -3.</em>
![\frac{-3y}{-3}=\frac{15}{-3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3y%7D%7B-3%7D%3D%5Cfrac%7B15%7D%7B-3%7D)
![y=-5](https://tex.z-dn.net/?f=y%3D-5)
Therefore, at x = -3, the value of y = -5. Hence, f(-3) = -5.
Answer:
f(-3) = -5
