Algebraic Word Problems
Professor Dave Explains
Guided Notes
Key concepts students will learn:
- •
In algebraic word problems, it is important to assign variables to represent unknown quantities and then construct equations based on the given information.
- •
When solving word problems with consecutive multiples, if the first number is X, then the next consecutive multiple of three would be X + 3, and the one after that would be X + 6.
- •
If J = R + 6 and 2R + 3J = 68, you can substitute R + 6 for J in the second equation and then distribute and simplify to solve for R.
