A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the smaller number. Which equations represent the situation?

Respuesta :

Answer:

The equations represent the situation is [tex]y=2x+6[/tex] and [tex]y=5+3x[/tex].

Step-by-step explanation:

Consider the provided information.

First convert the statement into mathematical representation.

Consider the smaller number is x and the larger number is y.

y, is equal to twice the sum of a smaller number and 3.    

This information can be written as: [tex]y=2(x+3)[/tex]

Which can be further solve as:

[tex]y=2x+6[/tex]

The larger number is also equal to 5 more than 3 times the smaller number.

This information can be written as: [tex]y=5+3x[/tex]

Thus, the equations represent the situation is [tex]y=2x+6[/tex] and [tex]y=5+3x[/tex].

Which can be further solve as:

[tex]2x+6=5+3x[/tex]

[tex]x=1[/tex]

Now, substitute the value of x in [tex]y=5+3x[/tex].

[tex]y=5+3[/tex]

[tex]y=8[/tex]
