Let Jenny = J

Let Mica = M

J = M + 4

Now you have to represent 5 years ago

J - 5 = 2*(M - 5)

J - 5 = 2M - 10                Substitute J = M + 4 Into this equation

M + 4 - 5 = 2M - 10        Combine terms on the left

M - 1 = 2M - 10               Add 10 to both sides    

M - 1 + 10 = 2M              Combine one the left

M + 9 = 2M                    Subtract M from both sides

9 = 2M - M              

9 = M                             Answer Miki

J = M + 4                       Substitute Miki's age for M

J = 9 + 4                         Answer Jenny

J = 13

Answer:

Jenny = 13

Mika = 9
