Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?

Answer 1

mary=10 jack=15

Explanation:

After 4 years Mary (x+4), Jack's age (x+5) + 4.

sum of the ages after 4 years :(x+4) + (x+5) +4=33

Simplifying the equation:

2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age

10 + 5 = 15 which is Jack's age.
