The system of equations:
2 y = - x - 1
2 y = x + 5
---------------------
- x - 1 = x + 5
- 2 x = 5 + 1
- 2 x = 6
x = - 6 : 2
x = - 3
2 y = - 3 + 5
2 y = 2
y = 1
The solution is ( - 3 , 1 ).
Answer: The x-coordinate of the solution to the system is: x = - 3.

Using a graphing calculator, we can see the graph of the function y = x²-4x+1:
as we can see, the vertex of the function is (2,-3), and the solutions are (0.3,0) and (3.7,0)
Answer:
6x+9
Step-by-step explanation:
Sin 3θ = 0
3θ = sin^-1 0 = nπ
θ = nπ/3
