Answer:
The solution to the system of equations is:
The graph is attached below.
Step-by-step explanation:
Given the system of equations
Let us solve the system of equations using the elimination method
Arrange equation variables for elimination
Multiply y + 2x = 5 by 2: 2y + 4x = 10
subtracting the equations
solve 6x = 18 for x
Divide both sides by 6
simplify
For 2y - 2x = -8 plug in x = 3
Add 6 to both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
The graph is attached below.
