What is linear equation in one variable?
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
According to the given question.
The amount of money charged by phone service = $27.28
The additional amount charge by phone service for each text = $0.23
Amount of money have to pay Tim = $33.03.
Let x text messages sent by Tim.
Therefore,
The whole condition can be represented by the linear equation in one variable
[tex]0.23x + 27.28 = 33.03...(i)[/tex]
Solve the equation (i) for x.
[tex]0.23x = 33.03 - 27.28[/tex]
⇒[tex]0.23x = 5.75[/tex]
⇒[tex]x = \frac{5.75}{0.23}[/tex]
⇒[tex]x = 25[/tex]
Hence, Tim sent 25 text message last month.
