The system of equations
has exactly one (x, y) pair for its solution
2x + y = 8
1. If we double each side of the second equation, 2x + y = 8, we have 4x + 2y = 16. Explain why the same (2, 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 using the draw tool below, or by inventing a situation that the equations represent.
