Question

Today,Tien's age is 1/4 of jordan's age.in 2 years,Tien's age will be 1/3 of jordan's age. how old is jordan today.

Answer 1

Jordan is 16. you have to solve the system: 1) t= 1/4 j; 2) (t+2)= 1/3(j+2). So you will get: 1/4j+2=1/3j+2/3 --> 1/4j-1/3j= -2+2/3..... solving for j you will get j=16.

t today=4

1) 4=1/4* 16

2) 6= 1/3*(16+2)
