Word problems commonly include mathematical modelling questions, where data and information about a certain system is given and a student is required to develop a model. For example: Jane had $5.00, then spent $2.00. How much does she have now?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal. If we subtract the same number from both sides of an equation, both sides will remain equal.
Do unto one side of the equation, what you do to the other!
If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal.
One of the biggest reasons why some students struggle with word problems is because they aren’t just regular math problems – they involve reading! And more than that, students have to be able to fully comprehend what is happening in the problem in order to figure out how to solve it.
The best way to determine what operations you will need to introduce to the values that are presented in the problem is to read the problem carefully and look for words that indicate what is being asked of you. There are many different types of words and phrases that will indicate a certain operation.

Graphing. Graphing is one of the simplest ways to solve a system of linear equations. All you have to do is graph each equation as a line and find the point(s) where the lines intersect. These equations are already written in slope-intercept form, making them easy to graph.
