Age word problems typically involve comparing two people’s ages at different points in time, i.e. at present, in the past, or in the future. let’s get familiar with age word problems by working through some examples. part i: age word problems solvable with one variable. example 1: tanya is 28 years older than marcus.
Algebra Age Word Problems Ii Youtube 7.9 age word problems one application of linear equations is what are termed age problems. when solving age problems, generally the age of two different people (or objects) both now and in the future (or past) are compared. the objective of these problems is usually to find each subject’s current age. Solve this equation by simplifying it step by step: (after brackets opening at the right side) (after moving variable terms to the right and constant terms to the left) (after combining like terms) thus you got that kevin's present age is years. check. if kevin's present age is 7 years, then margaret is years old now. Solution: step 1: set up a table. step 2: fill in the table with information given in the question. john is twice as old as his friend peter. peter is 5 years older than alice. in 5 years, john will be three times as old as alice. how old is peter now? let x be peter’s age now. Example 1: five years ago, john’s age was half of the age he will be in 8 years. how old is he now? solution: step 1: let x be john’s age now. look at the question and put the relevant expressions above it. step 2: write out the equation. isolate variable x. answer: john is now 18 years old.
