the sum of a 4 times Jonas age and 3 times Tim's age is 47.Tim id 1 year less than twice as old as old as Joan.Find each of their age

Answer 1

4J + 3T = 47 <--- 4 time Joans' age and 3 times Tim's age is 47

T = 2J-1 <-- Tim IS 1 year less than twice AS OLD as JONAS

4J + 3(2J-1) = 47

4J + 6J - 3 = 47

10J - 3 = 47

10J = 50

J=5

JONAS is 5.

Tim is 2(5)-1 = 10-1 = 9
