Algebraic Word Problems
Professor Dave Explains
Guided Notes
Key concepts students will learn:
- •
In algebraic word problems, we assign variables to represent unknown quantities and construct equations to represent the relationships between them.
- •
If there are three brothers whose ages are consecutive multiples of three and the sum of their ages is thirty-six, we can represent their ages as X, X + 3, and X + 6.
- •
When solving algebraic word problems, the trickier part is constructing the equations from the given information, while solving them is the easier part.
