Tim is 4 years older than one-third of Juan's age.
In 10 years, Juan will be 6 years older than twice as old as Tim is now.
How old is each now?
T = 4 + (1/3) J —>> 3T = 12 + J (eq 1)
J + 10 = 6 + (2) T —>> 2T = 4 + J (eq 2)
subtract (eq 2) from (eq 1) T = 8
substitute 8 for T in (eq 1) 24 = 12 + J
J = 12
check answers
8 =? 4 + 4 12 + 10 =? 6 + 16
8 = 8 true 22 = 22 true
