Respuesta :

Answer:

26-12=14

Step-by-step explanation:

sister sends 14 texts per day

Using a system of equations, it is found that she sends about 14 text messages a day.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: The number of text messages you send in a day.
  • Variable y: The number of text messages your sister sends in a day.

You send about 12 text messages a day, hence x = 12.

Together, you send a total of about 26 messages per day, hence:

x + y = 26

12 + y = 26

y = 14

She sends about 14 text messages a day.
