Liz's present age --- x
Jake's present age --- x+15
Naida's present age --- x-19
Guessing that your typo is: Find their present ages if Jake's age in ....
Jake's age 4 years from now: x+15 + 4 = x + 19
naida's age 7 years from now = x-19 + 7 = x - 12
liz's age 11 years ago = x-11
Find their present ages if Jake's age in 4 years is 5 more than the sum of naida's age 7 years from now and liz's age 11 years ago
---> x+19 = (x-12) + (x-11) + 5
x+19 = 2x - 18
x = 37
State their present ages by going back to my definitions
Verify my answer after checking my arithmetic
Jake is 15 years older than liz while naida is 19 years younger than liz. Find their present ages if age in 4 years is 5 more than the sum of naida's age 7 years from now and liz's age 11 years ago
