x = Jordan's age
x+24 = Anna's age (she is 24 years older than Jordan)
x+4 = Jordan's age in 4 years
x+28 = Anna's age in 4 years
Anna's age in 4 years will be ("is equal to") twice Jordan's age in 4 years:
Solve using basic algebra....
Using logical reasoning and simple mental arithmetic....
The difference between their ages is 24 years
When Anna is twice as old as Jordan, their ages will be 24 and 48
Since that will be 4 years from now, their current ages are 20 and 44
