Chapter 1: Applications of Equations and Inequalities Dr. Raja Mohammad Latif In this chapter, we will apply equations to various life situations. We will do the same with inequalities, which are statements that one quantity is greater than, less than, no greater than, or no less than some other quantity. 1.1 Applications of Equations

Problems 1 ; 11 ; 13 ; 21 ; 25 ; 35 ; 37 Algebraic methods are very useful in solving applied generally stated in verbal form; before we can make use of our algebraic tools, it is necessary to translate the verbal statements into corresponding algebraic statements. The following step-by-step procedure will very often be helpful in carrying out this process. Step 1 Represent the unknown quantity that is, the quantity to be determined by an algebraic symbol, such as x: In some problems, two or more quantities must be determined; in such cases we chose only one of them as x: Step 2 Express all of the other quantities involved in the problem, if there are any, in terms of x: Dr. Raja Latif, Dep Math KFUPM
