Question

A number, y, is equal to the difference of a larger number and 3. The same number is one-third of the sum of the larger number and 9. Which equations represent the situation?

Answer 1

Equations:

Let x=the larger number

1. y=x-3
2. y=1/3(x+9)

Answer 2

Answer:

The equations are $y = x -3\texttt{ and }y=\frac{x+9}{3}$

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

          $y=\frac{x+9}{3}$

So the equations are $y = x -3\texttt{ and }y=\frac{x+9}{3}$
