This is a collection of word problem solvers that solve your
problems and help you understand the solutions. All problems are
customizable (meaning that you can change all parameters). We try
to have a comprehensive collection of school algebra problems.
The good news is that the steps to solve word problems are always the same.
The bad news is that you may have to think pretty hard.
Here's a run down on what you need to do for a typical age word problem, with a little example.
The older brother Bob is two year older than his little sister Alice.
Taken together, the sum of their ages is 8.
Read the problem carefully.
Get rid of clutter
Identify key variables (unknowns).
Eliminate unneeded variables.
Use the text of the problem to write equations.
Solve the equation.
Find the remaining variables.
The older brother Bob is two year older than his little sister Alice. Taken together, the sum of their ages is 8.
Bob is two years older than Alice. Bob's age plus Alice's age = 8.
Bob's age B and Alice's age A
Get rid of B. Bob is 2 years older than Alice, so you can use A+2 instead of B
