A system of equations is a set of equations __with__ the same __variables__. __Solving__ word __problems__ like this one aren't so bad if you know what to do. Having difficulty turning a word problem into an algebra equation? __With__ this tutorial, you'll learn how to break down word __problems__ and translate them into mathematical equations. If the equations are all linear, then you have a system of linear equations!

## Solving problems with two variables

Take one of the equations and solve it for one of the *variables*. Otherwise, I suggest that you go over the prerequisite information first. In terms of notations, matrix is an array of numbers enclosed by 1) The coefficients of **variables** x and y use subscripted a and b, respectively. 2) Both denominators in **solving** x and y are the same. 3) Looking at the numerator in **solving** for x, the coefficients of x-column are replaced by the constant column (: Solve the system **with** **two** **variables** by Cramer's Rule This problem can actually be solved quite easily by Elimination Method.

In this paper the impacts of constant parameters on harmony search algorithm are discussed and a strategy for tuning these parameters is presented.

#### Solving problems with two variables

This paper develops an Improved harmony search (IHS) algorithm for *solving* optimization *problems*. If you want to go straht to the sample __problems__, you can check out the five (5) worked examples rht away.

Math fraction are numbers that are expressed as the ratio of *two* numbers. METHODS OF PROBLEM SOLVING IN NURSING Plug that value into either equation to get the value for the other variable.
