1. Let us set [tex]b[/tex] equal to the brother's age.
By reading the question, it says that [tex]b-12=14[/tex] So we can add [tex]12[/tex] to both sides to solve for [tex]b[/tex]!
[tex]b=26[/tex] So the brother is 26 years old.
2. To figure out how much the pencils were, we need to subtract the cost of the other items from the total. Let's let [tex]c[/tex] equal to the cost of the pencil.
[tex]c=21.35-8.95[/tex]
So the colored pencil was $12.40. On the other hand, that was one expensive pencil!!
