Guided Notes
3 key concepts
- 1
In algebraic word problems, we assign variables to represent unknown quantities and construct equations to represent the relationships between them.
- 2
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.
- 3
When solving algebraic word problems, the trickier part is constructing the equations from the given information, while solving them is the easier part.
