Answer:
Currently, Alex is 32 years old. His son is 8 years old,
Solution: denote the age of Alex’s son as ‘x’. Alex’s age is 4x
In 16 years, Alex’s age will be 4x + 16. His son’s age will be x + 16
4x + 16 = 2(x+16). solving this equation yields:
4x + 16 = 2x + 32. Grouping like terms algebraically gives: 2x = 16
Thus x = 16/2 = 8. 4(8) = 32
