Linear equations and inequalities : Systems of linear equations and inequalities Quiz

Quiz
*Theme/Title:	Systems of linear equations and inequalities
* Description/Instructions
Linear equations and inequalities generally contain unknown values that are not raised to powers. In other words, you won't see exponents. You will see systems of equations that contain more than one unknown value, usually represented by a letter such as x. You might be asked to solve for two unknowns given two equations, or you might have to solve for one unknown in terms of another. Often you will need to use substitution or elimination to "weed out" the unknown terms that are not asked about. You might also need to translate from a word problem into one or more equations or inequalities before you can solve a problem. There is also a link between linear equations and geometry, as any equation in the form y = mx + b (in which m represents the slope and b represents the y-intercept of a line) is a linear equation.
