Answer:
The equations are [tex]y = x -3\texttt{ and }y=\frac{x+9}{3}[/tex]
Step-by-step explanation:
Let the number be y and larger number be x.
A number, y, is equal to the difference of a larger number and 3.That is
y = x -3
The same number is one-third of the sum of the larger number and 9. That is
[tex]y=\frac{x+9}{3}[/tex]
So the equations are [tex]y = x -3\texttt{ and }y=\frac{x+9}{3}[/tex]
