Solving Algebra Word Problems
A series of free Intermediate Algebra Video Lessons from Brightstorm online Algebra series.
Applied Linear Equations:
Investment Math Problems
In Algebra II and in the real world, sometimes we need to solve investment math problems by using linear equations. When solving word problems using linear equations, we first need to pull out the relevant information and put it into equation form. When working with investment math problems, we are usually asked to calculate amounts earned by interest on original principal amounts.
Applied Linear Equations:
Tax Math Problems
In Algebra II and in the real world, sometimes we need to solve tax math problems by using linear equations. When solving word problems using linear equations, we first need to pull out the relevant information and put it into equation form. When working with tax math problems, we are usually asked to calculate sales tax rates or the total cost of an item with tax.
Applied Linear Equations: Distance Problem,
Rate Word Problems
To solve rate word problems, knowledge of solving systems of equations is necessary. Rate word problems include problems dealing with rates, distances, time and wind or water current. Other types of word problems using systems of equations include money word problems and age word problems
Linear Equation Collection Problems
In Algebra II and in the real world, sometimes we need to solve collection math problems by using linear equations. When solving word problems using linear equations, we first need to pull out the relevant information and put it into equation form. When solving linear equation collection problems, we are usually asked about numbers of certain types of coins. These types of problems are sometimes called coin word problems.
Consecutive Number Problems
In Algebra II, we sometimes see consecutive number problems. Consecutive number problems may ask us to find a sum of integers or the specific integers themselves. To solve these problems, we set up a linear equation or a system of linear equations and then solve for a variable. These types of problems are often found on the SAT and ACT.
