Question from Dee: Blair is 12 years younger than Serena right now. |
Hi Dee,
Suppose Blair is $b$ years old and Serena is $s$ years old. Blair is 12 years younger than Serena. Write this fact as an equation in $b$ and $s.$
Five years ago how old was Blair? How old was Serena? At that time Serena's age was five times Blair's age. Write this fact as an equation in $b$ and $s.$
Solve the two equations.
Make sure you check your answer.
