Answer:
James is 12 years old
Joe is 22 years old
Explanation:
Joe is 10 years older than James. In 8 years, twice Joe's age will equal three times James's age.
LEt x be the age of James
x+10 be the age of Joe
In 8 years, James age becomes x+8
In 8 years, Joe's age becomes x+10+8 = x+18
Twice Joe's age is equal to 3 times of James's age
2(x+18)= 3(x+8)
2x+ 36=3x+24
Subtract 2x from both sides and subtract 24 from both sides
x=12
James is 12 years old
Joe is x+10 = 22 years old
