Algebra TutorialWORD PROBLEMSWord problems are easy to solve if you follow these three steps :1 Read the problem at least twice; underline the key words that strike you or appears tricky to you.2 Translate the word statements into mathematical symbols and equations or inequalities;.---that is ,set up equations or inequalities.3 Think for a momentget the mathematical procedure and proceed to solve the problem.Among these steps, the second step translating word statements into math language-- appears difficult. This tutorial with several examples will make this process easy---at Algebra-1 level.----------------------------------------------------------------------------------------------------Now let us start with examples:1 Sarah is elder to John by 4 years. The sum of their ages is 26. Find the ages of Sarah and John. Here the unknowns are Sarahs age and Johns age Let us use symbols x and y for these unknowns. X ---the age of Sarah Y --the age of JohnLet us set up the equations.The sum of their ages is 26. - X + Y = 26Sarah is elder to John by 4 years. X= Y + 4Now we have two equations in two unknowns. Let us solve :Substitute for x in the first equation: Y + 4 + Y = 26 2Y + 4 = 26 2Y = 22 Y + 11
