Question

The graph below shows a system of equations:

Draw a line labeled 2 y equals minus x minus 1 by joining the ordered pairs negative 3,1 and 3, negative 2. Draw a line labeled 2 y equals x plus 5 by joining the ordered pairs negative 3, 1 and 3, 4. The x-coordinate of the solution to the system of equations is _____.

Answer 1

homer is correct but next time post a graph.

Answer 2

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.
