Question 7 2 pts
The system of equations
{4x + 6y = 24
2x+y=8
has exactly one (x, y)
pair for its solution.
Part A. If we double each side of the equation, 2x + y = 8, we
have 4x + 2y = 16. Explain why the same (x, y) pair that is the
solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger
diagrams, or by inventing a situation that the equations
represent.
Part B. If we add the two equations in the original system, we
have 6x +y = 32. Explain why the same (x, y) pair is also a
solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.
