What is the 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 initial fee charge by a Babysitter's block  for one household is $25

And for one hour fee charged by Babysitter's block is $15.

So the total cost changed by Babysitter's block for n number of hour

= $25 + n($15)

And, the fee charged by super sitters for one hour = $20

Let for x hours of service, both babysitting services would cost the same.

For finding the value of x, we have to solve a linear equation in one variable.

25 + x(15) = 20x

⇒ 25 = 20x - 15x

⇒ 25  = 5x

⇒ x = 5

Hence, for 5 hours of service, both babysitting services would cost the same.
