### Systems of linear equations week5 discussion

1. 1. SYSTEMS OF LINEAR EQUATIONS AND INEQUALITIES Week 05: Solving Word Problems Prepared by: Jojo M. Lucion DISCUSSION When you solve word problems you have to translate from English into mathematical sentences and phrases. When a word problem involves two conditions, we may be able to translate each condition into an equation. The numbers that satisfy both equations at the same time represent the solution of the word problem. A. Number Relation Problems Example 1 In the recent achievement test Jose has 6 fewer mistakes than Maria. Twice the number Maria's mistakes is 5 more than three times the number Jose has. How many mistakes does each have? Let x = the number of mistakes Maria has y = the number of mistakes Jose has
2. 2. Solve for u t+u=6 2+u=6 u=6-2 B. Business and Investment Problems
3. 3. C. Geometric Problems
4. 4. D. Motion Problems
