What is an equation?
In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Number of problems assigned to Paulina = 42
Number of problems completed by Paulina = 24
Number of remaining problems to be finished per hour = 9
Therefore number of remaining problems finished in h hours = 9h
Hence, we can write,
Total number of problems completed + Total number of problems remained = Total problems assigned
Hence the Equation is given as,
24 + 9h = 42
⇒ 9h = 42 -24
⇒ 9h = 18
⇒ h = 2
Hence, Paulina will complete her math homework in 2 hours.
