Respuesta :

Answer:

The number is -11.

Step-by-step explanation:

3 times a number:

A number is x, and thus, 3 times a number is 3x.

Subtracted from 7 times the number

We have 3x.

Subtracting from 7 times the number is the same as subtracting from 7x. Thus 3x - 7x = -4x.

The result is 44. What is the number?

[tex]-4x = 44[/tex]

[tex]4x = -44[/tex]

[tex]x = -\frac{44}{4}[/tex]

[tex]x = -11[/tex]

The number is -11.
