Yuson must complete 30 hours of community service.
She does two hours each day.
We are asked to write a linear equation to represent the hours she has left after x days.
We can write the following linear equation
Where 30 represents the total hours of community service that Yuson has to complete.
2 represents the hours she works each day.
x represents the days.
We can also solve this equation to find how many days will it take her to complete the community service.
