The sum of liz's and melinda's ages is 28. if liz was 1/3 melinda's age 6 years ago, how old will liz be next year?
Mrrafil [7]
The first thing we must do for this case is to define variables:
 We have then:
 x: liz's age
 y: melinda's age
 We now write the system of equations:
 x + y = 28&#10;&#10;x-6 = (1/3) (y-6)
 By solving the system graphically we have that the age of each one is currently:
 x = 10&#10;&#10; y = 18
 Next year, the age of liz is:
 x + 1 = 10 + 1 = 11&#10;
 Answer:
 
Next year, Liz's age is 11 years.
 
Note: see attached image for the graphic solution.
